Question

what is the condition for theta if sin theta square+cos theta square=1 where theta € Q¹​

Answer 1

Answer:

Theta should be between 0° and 90°. You can keep on adding 360° because it won't matter.

For example, 0+720° and 90°+720° can also be the range for theta.

If you are below class 11 just write theta should be between 0° and 90°.
