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.

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.

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 …

Apr 4, 2014 · Ignoring constants when finding derivatives of trig functions Ask Question Asked 12 years ago Modified 6 years, 7 months ago

If you were computing the derivative of the latter, then your computations are correct; the derivative is $2\pi\sin (\pi x)\cos (\pi x)$. But if you were asked for the derivative of $\sin\Bigl ( (\pi x)^2\Bigr)$, …

May 26, 2015 · I was inspired by this question to try and come up with geometric proofs for the derivatives of basic trig functions--basically, those that have simple representations on the unit circle …

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 …

Apr 12, 2015 · It seems to be that when you go from trig to hyperbolic and consider the derivatives, the derivatives always use the same function (although in hyperbolic terms rather than trig terms). But …

Oct 7, 2020 · Since all the trig functions have formulas in terms of the sine function, the product rule and the chain rule guarantee that if the derivative of the sine function stays in Trig World (my favorite …
