Plz help me solve this sum, I will really appreciate it.

Plz help me solve this sum, I will really appreciate it.

solve the equation for the solutions over the interval [0 degrees, 360 degrees) 6sec2xtanx=12tanx I am unsure of where to begin.

cos(3theta)=-1 solve for exact solutions over the interval [0,360 degrees] I am having trouble finding a place to start.

I am getting stuck at 7 plus or minus sqrt 309 / 26 13sin^2x-7sinx=5 solve for interval [0,360degrees]

find an equation of a sinusoidal function that has minimum at the point (2,1) has a period of 8 and an amplitude of 3

cos(4θ)-cos(6θ) on the interval 0≤θ<2π

Solve the equation on the interval 0 less than or equals theta less than 2 pi 0≤θ<2π. 2 cosine theta plus 1 equals 0 2cosθ+1=0

you haveto change it from radians to degrees

-sin(3x+2π)+cos(-3x)•tan(π-3x)

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

If sin(x) = 1/4 and x is in quadrantI,find the exact values of the expressions without solving for x. (a) sin(2x) (b) cos(2x) (c) tan(2x)

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...

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

Plz help me to prove this...

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

How do you get the solution?

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

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...

Find the exact value algebraically of sin(105°)
