-sin(3x+2π)+cos(-3x)•tan(π-3x)

f(x) = 5sin (-4x)-3 in the domain 0<x<2 pi i know how to find the derivative f'(x) = -20 cos (-4x) but i am unsure as to how you solve this for critical values: 0=-20cos(-4x) (maximum...

There are 2 possible answers I can choose from. Either Bounded or Continuous

Find the remaining trigonometric functions of θ based on the given information. cos θ = 1 2 and θ terminates in QIV

I know that the range of cos(x) is [-1,1], but I'm not sure how to calculate the range for this function.

How do you get the solution?

1.A mass on a spring moving up and down is an example of harmonic motion. If the height of the spring mass system follows the function h(t)=5cos2t , where t is the time in seconds and h is the height...

sin(x) + sin(3x) = 4 sin(x) cos^2(x)

16 cos(2θ) = 16 cos^2(θ) − 9
