You can use the Pythagorean identity to solve this:(sin theta) squared + (cos theta) squared = 1.


How do you solve 2 sin squared theta equals one fourth?

2 sin^2 theta = 1/4 sin^2 theta = 1/8 sin theta = sqrt(1/8) theta = arcsin(sqrt(1/8))


How do you prove cot squared theta plus cos squared theta plus sin squared theta scs squared theta?

Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.


How do you solve sin2 theta if sin theta equals 3 over 5 and theta is in the first quadrant?

If sin (theta) is 3/5, then sin2 (theta) is (3/5)2, or 9/25.


Can you solve sin 2 theta equals 0?

If sin2(theta) = 0, then theta is N pi, N being any integer


Is sin squared theta and sin theta squared the same?

Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.


What does 2sin squared theta equal and why?

It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!

If a cos theta plus b sin theta equals 8 and a sin theta - b cos theta equals 5 show that a squared plus b squared equals 89?

Well, darling, if we square the first equation and the second equation, add them together, and do some algebraic magic, we can indeed show that a squared plus b squared equals 89. It's like a little math puzzle, but trust me, the answer is as sassy as I am.


How do you figure this out Sin theta equals 0.0138 so theta equals what?

theta = arcsin(0.0138) is the principal value.


Which basic trigonometric identity is actually a statement of the pythagorean theorem?
