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 …

Jan 10, 2019 · I'm a bit confused about how the inverse trig functions are differentiated. From a website: We have the following relationship between the inverse sine function and the sine function. $$\\sin...

May 22, 2021 · Here is a trick I use to remember the derivatives and antiderivatives of trigonometric functions. If you know that \begin {align} \sin' (x) &= \cos (x) \\ \sec' (x ...

Jul 17, 2020 · I know how to use geometry to find the derivatives of $\sin x$ and $\cos x$ like this: We can use the fact that we know the tangent of the circle to show that $\frac {d} {dx}\cos (x)=\sin (x)$. …

– sarah Apr 10, 2017 at 23:49 If you've ever seen the derivation using implicit derivatives for the inverse trig functions, the development is basically identical – Triatticus Apr 11, 2017 at 0:00 Add a comment

Jun 27, 2020 · Why the derivative of inverse secant has an absolute value? Ask Question Asked 5 years, 8 months ago Modified 4 years, 6 months ago

Feb 2, 2020 · 3 Since you are asking under the term "calculus", my guess is that the reason why you think that you have heard "reciprocal" and "inverse function" being used interchangeably is that, in …

Feb 21, 2011 · The general way is to know the derivatives of the inverse trigonometric functions, and then apply the Chain Rule.

3 Use the identity $\sin x = -i\sinh x$. Then your formula gives $\sinh x =\ln| \sqrt {x^2+1}+x|$. By restricting hyperbolic sine to the reals and, thus, its inverse to positive reals, you can drop the …
