Prove that y=sin(x) then dy/dx=cos(x)
Answers
Step-by-step explanation:
You will have to use the limit defition of the derivative. Brainly does not have calculus symbols, which is very unfortunate, so I can only use my words. Take the limit as the change in 'x' approaches zero. You will have:
[tex] \frac{sin(x + {x}^{.} ) - sin(x)}{ {x}^{.} } [/tex]
If you let "x dot" equal zero as the limit requires, you will get 0/0 which is indeterminate. Break up the first term using the formula for the sine of a sum. You get:
[tex] \frac{sin(x)cos( {x}^{.} ) + sin( {x}^{.})cos(x) - sin(x) }{ {x}^{.} } [/tex]
Factor a sin(x) from the first and third term to get:
[tex] \frac{sin(x)(cos( {x}^{.}) - 1 ) + sin( {x}^{.})cos(x) }{ {x}^{.} } [/tex]
Use the linearity to break the limit into two parts:
[tex] \frac{sin(x)(cos( {x}^{.}) - 1 )}{ {x}^{.} } + \frac{sin( {x}^{.} )cos(x)}{ {x}^{.} } [/tex]
First term converges to zero, second term converges to cosine. Therefore proving the derivative of sine is cosine

maths j2 a road is 300km long is drawn to a scale of 1cm represents 50km . what is it's length on drawing?
Answers
Answer: 6cm.
Step-by-step explanation:
Strategy 1 (in-head thinking)
300 divided by 50 would be 6, multiply 6 by 1 and get 6cm.
Strategy 2 (proportions)
First, set up a proportion.
We know that 1cm = 50km, so we put them on a fraction (whichever is denominator/numerator doesn’t affect the process)
However, we don’t know how much cm equals 300km, so we turn that into a variable, in this case x.
1cm x cm
——— ———
50km 300km
To solve a proportion, go diagonal to where the variables have already been filled in. You can’t so 50km and x cm, as you don’t know x. You can do 300km however. To start, multiply 1 and 300, to which you get 300. Then, multiply 300 by the 50km and you’ll get x. That’ll equal to 6.
So in conclusion, your answer is 6.

Muna claims that the expression (8)(16) + (8)(12) + (16)(12) represents the
surface area, in square inches, of the right rectangular prism shown. Is Muna
correct? Explain.
Answers
The surface area of a right rectangular prism is the amount of space on it.
Muna's claim is incorrect
How to determine the surface area?
The surface area of a right rectangular prism is calculated as:
A = 2 * (lw + lh + wh)
So, we have:
A = 2 * (8 * 16 + 8 * 12 + 16 * 12)

18. a gamer played four games in 6 hours. she played each game for the same amount of time. how much time did she play each game on
a.2/3 hours
b. 1 hour
c. 1 1/2 hour
d. 2 hours
Answers
Answer:
c. 1 1/2 hours
Step-by-step explanation:
6 hours / 4 games = 1 1/2 hours per game
Another way to think of it:
1 hour = 60 minutes
6 hours = 6 hours x 60 minutes per hour = 360 minutes
360 minutes / 4 games = 90 minutes per game
90 minutes per game / 60 minutes per hour = 1.5 hours
1.5 hours is the same as 1 1/2 hours
So, the answer is c. 1 1/2 hours

A container manufacturer plans to make rectangular boxes whose bottom and top measure 4x by 3x. The container must contain 48in.3 The top and the bottom will cost $1.80 per square inch, while the four sides will cost $3.70 per square inch.
What should the height of the container be so as to minimize cost? Round your answer to the nearest hundredth.
Answers
The height of the container that will be able to minimize the cost will be 3.08cm.
How to calculate the height?The volume of the box will be:
= (3x)(4x)h
= 12x²h
From the information given, we are told that the container must contain 48in³. Therefore,
48 = 12x²h
h = 4/x²
The function cost will be:
= 3.50(2)(12x²) + 4.40(14x)h
= 84x² + 61.6x(4/x²)
= 84x² + 246.4/x
We'll use the first derivative. This will be:
dC/dx = 168x - 246.4/x²
x = 1.14.
Therefore, the height will be:
h = 4/x² = 4/1.14² = 3.08cm
In conclusion, the height is 3.08cm.

The bandit is attacking as pictured in the figure below:
The unit circle is shown. There is an angle 30 degrees counterclockwise from the positive y axis. An image of a bandit is shown at the point of intersection between the angle and unit circle.
What is the angle of fire in standard position on the unit circle in both degrees and radians?
120°; pi over 6 radians
120°; 2 pi over 3 radians
30°; pi over 3 radians
30°; 2 pi over 3 radians
Answers
The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
How to calculate the angle?
It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.
In this case, the value of the angle will be:
= 12π/18
= (12 × 180) / 18
= 12 × 10
= 120°
Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
