WebApr 14, 2024 · Now to calculate the integral of tan x between the interval 0 to π/2, we just have to replace π by π/2. Therefore, ∫ 0 π 2 tan x d x = ln ( sec x) 0 π 2. Now, ∫ 0 π 2 tan x d x = ln ( sec π 2) – ln ( sec 0) Since sec 0 is equal to 1 and sec π/2 is equal to 0, therefore, ∫ 0 π 2 tan x d x = 0. Therefore, the definite integral ...

WebProof Strategy: Make in terms of sin's and cos's; Use Substitution. 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 The six trigonometric functions are defined for every real number, except, for some of them, for angles that differ from 0 by a multiple of the right angle (90°). Referring to the diagram at the right, the six trigonometric functions of θ are, for angles smaller than the right angle: In the case of angles smaller than a right angle, the following identities are dire…
WebMay 25, 2016 · Make the substitutions into the tangent formula: arctan(x) ± arctan(y) = arctan( x ± y 1 ∓ xy) So, your identity is a little bit off since the minus-plus sign ( ∓) is needed in the denominator instead of the plus-minus ( ±) sign. The minus-plus sign shows that the identity can be split as follows:
