Question

Solve following equation
for............., in terms of pi

Answer 1

4sinx - 7= 2cosecx

Answer 2

I recommend multiplying both sides by sin(x) to start off

Answer 3

tell me what you get

Answer 4

well cosec= 1/sin

so multiply every term by sin(x) and you get

\[4\sin^2(x) - 7\sin(x) = 2\]

so now you are solving a quadratic

Answer 5

4sin^2x-7sinx-2=0

Answer 6

let z = sin(x)

we have

4z^2 - 7z - 2 = 0

solve for z
