derivitive problems (1 Viewer)

hello all,

im having problems with taking the derivitive of constants and implicit differentiation

whats d/dx of pi(sinx)?

what do i do with the pi?

can i do implicit differentiation or is that only with "y"s??

thanks

pi is just a constant so you take it out. therefore d/dx = cos x

it amazes me you know implicit differentiation yet you can't differentiate this. for implicit you will need a function y = pi sinx, then y' =picosx. It looks exactly the same because implicit differentiation is intended for very hard 3u (unlikely to even come up) and 4u in conics.

thanks. i wasnt a 100 percent sure on what to do with the constant but now i do.

thanks

They don't teach implicit derivatives in 3unit although it might save time in a lot of questions.
