What is the derivitive of a sine wave?
Negative cosine f(x) = sin(x) f'(x) = -cos(x)
Could please differentiate 12x?
To differentiate something you multiply the power on the x with the number in front of it and then reduce the power by one in this case: 12x is the same as 12x^1 so the derivitive is 12*1*x^0 which is just 12
What is the derivitive of tangent?
It is sec2.
What is the correct formula for calculating the circumference of a circle?
[2 x pie x radius] or [pie x diameter]
What is the area of a circle with a radius of 13.25?
Main Answer: To find out the area of the circle you must square the radius. Here's the answer: I took pie as 3.141592 Area = pie x radius squared A = pie x 13.25 squared --> pie x (13.25 x 13.25) A = 551.5457455 Don't forget to put the units on (e.g. mm, cm, etc) and round to whatever number of decimal places this question asks for. Extra Info: Circumference of a circle = pie x diameter Area of a circle = pie x radius squared C herry pie's d elicious --> C = pie x d A pple pie's r 2 --> A = pie x r2
