What is the integral of tan?
What is the integral of tan?
tan x = – ln|cos x| + C.
What is the differentiation of tan?
The derivative of tan x is sec2x. When the tangent argument is itself a function of x, then we use the chain rule to find the result.
How do you find the Antiderivative of TANX?
3 Answers
- ∫g'(x)g(x)dx=ln|g(x)|+C. (You can verify this by substitution u=g(x) .) Now, let us look at the posted antiderivative.
- By the trig identity tanx=sinxcosx ,
- ∫tanxdx=∫sinxcosxdx. by rewriting it a bit further to fit the form above,
- =−∫−sinxcosxdx. by the formula above,
- or by rlnx=lnxr , =ln|cosx|−1+C=ln|secx|+C.

What is the proof strategy for integral tan?
1. Proof Strategy: Make in terms of sin’s and cos’s; Use Subtitution. u = cos x. substitute back u=cos x 2. Alternate Form of Result
How to find the integral of tan x dx?
tan x dx = sin x cos x dx set u = cos x. then we find du = – sin x dx substitute du=-sin x, u=cos x sin x cos x dx = – (-1) sin x dx cos x du u Solve the integral = – ln |u| + C substitute back u=cos x = – ln |cos x| + C Q.E.D. 2. Alternate Form of Result tan x dx = – ln |cos x| + C = ln | (cos x)-1| + C = ln |sec x| + C Therefore:
Which is an example of a tangent integral?
Of so many trigonometric integrals, we will see some examples for tangent integrals. Example 1. Integral of tan 2x. ∫ tan. . ( 2 x) d x =. We substitute the 2 x for u, we derive and we pass dividing the 2: u = 2 x ⇒ d u = 2 d x ⇒ d u 2 = d x. And we replace the terms for u:
