Usually, the goal is to get the unknown by itself, but here, because the unknown is nestled within a trig function, the goal is to isolate the trig function and use the inverse trig function to solve for the unknown. Using an inverse trig function is like working backward, finding an ...
Solving trig equations use both thereference anglesandtrigonometric identitiesthat you've memorized, together with a lot of the algebra you've learned. Be prepared to need tothinkin order to solve these equations. In what follows, it is assumed that you have a good grasp of the trig-ratio va...
1. Simplify the equation by using trigonometric identities if necessary.2. Isolate the trigonometric function on one side of the equation.3. Use inverse trigonometric functions to find the angle measure.4. Check your solution by plugging it back into the original equation....
We can simplify the term in the denominator of the integrand using following double angle formula and other trigonometric identities: 1−cos2x=2sin2xsinx=1cscx After simplification, we will use following integration formula to find the integral of the given function: ...
I came across a question that required me to solve for invariant points between a base trig function and the function after horizontal stretch. I can't remember the exact question right now, but I'm just wondering how I would go about solving it if I didn't know any trig identities or...
