Tan x+y proof

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: 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 ...
