Question

 sin^2 theta + cos theta =2 (Hint: Use the Pythagorean identity sin^2 theta +cos^2 theta =1 to replace sin^2 theta in the given equation).

Answer 1

first solve for sin^2theta in the second equation, do you know how?

Answer 2

0?

Answer 3

\[\sin^2\theta+\cos^2\theta=1\]therefore\[\sin^2\theta=1-\cos^2\theta\]
replacee the sin^2theta in ur first equation by the one i jus found

Answer 4

so 1-cos^2 theta +cos^2 theta =1

Answer 5

yes

Answer 6

so thats my answer?

Answer 7

but wait you wrote 1-cos^2 theta +cos^2 theta =1
its \[1-\cos^2\theta+\cos \theta =1\]

Answer 8

if u are asked to find theta, then u just solve for costheta and find the value of theta

Answer 9

=2*

Answer 10

\[1-\cos^2\theta+\cos \theta=2\]
