Question

sin^2(x)+cosx=2

Answer 1

"use the pythagorean identity sin^2(x)+cos^2(x)=1"

Answer 2

solve for x?

Answer 3

no solve the equation

Answer 4

can you check the question...as I think there is a typo

Answer 5

there is no typo

Answer 6

if the question is correct then using sin^2 = 1 - cos^2

you get

\[1 - \cos^2(x) + \cos(x) = 2\]

or

\[\cos^2(x) - \cos(x) + 1 = 0\]

which has no real solutions...

Answer 7

now you have a quadratic that can't be solved...
