Sine calculator; Sine function calculator; and Sin degrees calculator. FAQ What is the sin of 2 theta? The sine of 2 theta (2θ) equals 2 sin(θ)cos(θ). According to one of the sine properties: sin(2x) = 2sin(x)cos(x). So, if you know the values for the sine and cosine ...
For example, {eq}\sin ^{2} \theta + \cos^{2} \theta = 1, 1+ \tan^2 \theta = sec^{2} \theta, {/eq} etc. Here, {eq}\sin {/eq}, {eq}\cos {/eq}, {eq}\sec {/eq}, and {eq}\tan {/eq} are the trigonometric ratios....
