WebThe right hand side is a product of (cos x) 3 and (tan x). Now (cos x) 3 is a power of a function and so we use Differentiating Powers of a Function: `d/(dx)u^3=3u^2(du)/(dx)` With u = cos x, we have: `d/(dx)(cos … WebIf you look at the upper left of the original f (x) function, we see f (x) = cos^3 (x) = (cos x)^3. They really mean the same thing; it's just two different ways of writing the same thing. However, be careful about negative powers. For example, sin^-1 (x) is not the same as (sin x)^-1 or csc x.

WebThe four rules for the derivatives of the tangent, cotangent, secant, and cosecant can be used along with the rules for power functions, exponential functions, and the sine and cosine, as well as the sum, constant multiple, product, and quotient rules, to quickly differentiate a wide range of different functions. Supplemental Videos WebThe derivative of the cosine function is written as (cos x)' = -sin x, that is, the derivative of cos x is -sin x. In other words, the rate of change of cos x at a particular angle is given by -sin x. Now, the derivative of cos x can be …

WebHow Wolfram Alpha calculates derivatives. Wolfram Alpha calls Wolfram Languages's D function, which uses a table of identities much larger than one would find in a standard calculus textbook. It uses well-known rules such as the linearity of the derivative, product rule, power rule, chain rule and so on. Additionally, D uses lesser-known rules ... WebBy the way, it's cos^2+sin^2=1. On the unit circle (x^2+y^2=1) each point on the circle can be represented by the point (cos (theta),sin (theta)) because sin (theta)=opposite/hypotenuse but the hypotenuse is the radius which is 1, and the opposite=y. Therefore, sin (theta)=y.
