So essentially the reason that the ^2 doesn't go away is because the derivative of sec(x) has sec(x) as a part of it whereas the derivative of sin(x) is just cos(x) mike 5 years ago 2. 4) prove d dx secx= secxtanx remember that sec is de ned to be 1 cos so we can use the quotient rule to nd the derivative of sec: d dx secx = 1 cosx 0 = (1)0(cosx) (1)(cosx)0 (cosx)2. Sal finds the derivatives of sec(x) and csc(x) by writing them as 1/sin(x) or 1/cos(x) and using quotient rule.

Proof of cos(x): from the derivative of sine this can be derived just like sin(x) was derived or more easily from the result of sin(x) given : sin(x) = cos(x) chain rule. A step by step process would be appreciated :) upload failed please upload a file larger than 100 x 100 pixels we are experiencing some problems, please try again. Trigonometric derivative: how to derive sec^2(x) if this is your first visit, be sure to check out the faq by clicking the link above let u = secx therefore: du. The derivative of tan x is sec x times sec x (where sec x is the other one) the derivative of sec x is sec x times tan x (ie, the other one) see also definition of the secant (sec) trigonometric function.

To find the derivative of secant, we could either use the limit definition of the derivative (which would take a very long time) or the definition of secant itself. Sec x = 1/cos x and that's it, we are done the derivative of tan x is sec 2 x how to take the derivative of x^2: steps & tutorial calculating the derivative of ln(x)^2 6:55.
We know the derivative of g(x) = sec x is g'(x) = secx tanx, so we multiply 2sec x by secx tanx to get our answer the following shows what we did in a nice organized manner.

Therefore, let us examine the fundamental properties of the basic trigonometric functions, using the derivative of secx as an example suppose that x is a random number or angle the value, which is the inverse of the cosine of the angle (number), is called secant of x and is denoted by sec x: sex x = 1/cos x.
