it depends on the function, there are different rules you can use for different types

what if i have like, sin(3x^3 +1) how would i do that?

use the trig rules of differentiation, the derivative of sin is cos, the derivative of cosx is sinx and the derivative of sinx is cosx. Last the derivative of cosx is sinx, then the pattern starts over

then you need to use the chain rule for 3x^3+1

so, im gonna say, cosx(9x+1)?

oh wait, imeant 9x^2 +1

almost except you take the derivative of the outside function of sin(3x^3+1), disregard the 3x^3+1 and we will make that x, so the derivative of sinx is cos x.

so what would the final answer be?..youre answer is kinda confusing:p

then replace the x and the derivative is cos(3x^3+1). BEcause there is a function within sinx we must use the chain rule. Now you need to to multiply by the derivative of the inside function of (3x^3+1) which is 9x. The derivative of the while funtion should now be 9xcos(3x^3+1)
