Jun 26, 2015 · I'm still struggling to understand why the derivative of sine only works for radians. I had always thought that radians and degrees were both arbitrary units of measurement, and just now I'm …

Mar 6, 2021 · I remember the derivatives of trig functions by naming 3x basic right triangles in a specific way and using ONE simple multiplication. Just wondering if there are similar approaches to …

May 22, 2021 · These functions have the prefix co- in them for a reason: cosine is the sine of the co-angle, cotangent is the tangent of the co-angle, and cosecant is the secant of the co-angle.

Oct 16, 2012 · However, this answer is wrong, because you found that $\sin (\theta)$ has derivative $\cos (\theta)$ under the assumption that $\theta$ is measured in radians, and not in degrees. Here's …

Feb 15, 2012 · I could be incorrect but a trig function squared would be the result of the trig function with the angle value and then squared. Not the angle value squared, that would give a different answer.

Jan 30, 2021 · So, when you need to take the derivative of $\sin^2 (5x)$, it may be a bit easier to think of it as $ [\sin (5x)]^2$, then apply the chain rule. They both mean the same thing, it's just easier to …
