Question

I have the answer can somone please check me.
What is the derivative of m(x)=ktan(kx) where k is the constant

Answer 1

answer will be\[k^2(1+\tan^2 kx)\]is that what u got?

Answer 2

I got k^2cos^2(kx) is thatthe same thing

Answer 3

emm we have a formula as\[1+\tan^2 x=\frac{1}{\cos^2 x}\]so u will come up with\[\frac{k^2}{\cos^2 kx}\]

Answer 4

are u familiar with that formula? :)

Answer 5

yes ok I gotcha no thanks

Answer 6

ok :)
