- sin^2 theta = 1/2(1- cos(2 theta)) so has period pi. # We know the answer is pi. Let's see why. The period of sin(x) is 2pi and the period of sin (kx) is thus {2pi}/k. That doesn't tell us the period of sin^2 x until we apply one of the double angle formulas for cosine: cos(2 x) = 1 - 2 sin ^2 x sin^2 x= 1/2(1- cos(2 x)) The period of cos 2 x is pi by the rule, and the addition and.

sin 2 x MEANS (sin x) 2. Which you can calculate on your calculator. IMHO you are not the only one and not totally at fault to be confused - sin 2 x as far as I can see is a sort of mathematical slang, not strictly logical (so no wonder your calculator doesn't understand it either) which by its antiquity is let through and is universal - so there it is to get used to As per the sin theta formula, sin of an angle θ, in a right-angled triangle is equal to the ratio of opposite side and hypotenuse. The sine function is one of the important trigonometric functions apart from cos and tan. Here we will discuss finding sine of any angle, provided the length of the sides of the right triangle (The notation sin 2 (x) is equivalent to (sin(x)) 2.Warning: sin-1 (x) stands for arcsin(x) not the multiplicative inverse of sin(x).). By observing the graphs of sine and cosine, we can express the sine function in terms of cosine and vice versa

(For reasons I do not know, Algebra.com's formula software does not do theta, So I will be using alpha, , instead It's going to become 2 times 2 squared minus x squared. x squared is 2 sine theta, so x squared is going to be 2 squared sine theta squared. And now we can factor out the 2 squared. So this is going to be 2 times 2 squared times 1 minus sine squared theta. 2 times 2 squared, well that's just going to be 8, times cosine squared theta
