Deriv of sin and cos
WebJust for practice, I tried to derive d/dx (tanx) using the product rule. It took me a while, because I kept getting to (1+sin^2 (x))/cos^2 (x), which evaluates to sec^2 (x) + tan^2 (x). Almost there, but not quite. After a lot of fiddling, I got the correct result by adding cos^2 (x) to the numerator and denominator.

WebMar 24, 2024 · dy dt = − sint. Now, we substitute each of these into Equation 14.5.1: dz dt = ∂z ∂x ⋅ dx dt + ∂z ∂y ⋅ dy dt = (8x)(cost) + (6y)( − sint) = 8xcost − 6ysint. This answer has three variables in it. To reduce it to one variable, use the …
WebWell, if you have a negative function as -sin(y), you could take -1 out of a derivative, as it is a constant, so you get dy/dx(-1sin(y))= -1 dy/dx(sin(y))= -1 * cos(y)= -cos(y) As for the first part of you question (as far as I understood it), you had to see the sin(y) in terms of X so you will be able to tell the actual value of a derivative for any X.
