tan x pi 2 How do you use the sum and difference identities to find the exact value of tan 105 degrees How do you apply the sum and difference formula to solve trigonometric equations How do you evaluate sin 45 cos 15 cos 45 sin 15
We can not simply use the tangent of a sum formula because tan pi 2 does not exist See other answer for using the sum formula Verify tan x pi 2 cot x On the trig unit circle the value AT tan x rotates counterclockwise an arc of pi 2 and becomes BU cot x

This simplifies to tanx We use the addition formula for tangent tan A B tanA tanB 1 tanAtanB and the fact that tan pi 0 1 0 How do you prove csc theta times tan theta sec theta How do you prove 1 cos 2 x 1 cot 2 x 1 How do you show that 2 sin x cos x sin 2x is true for 5pi 6
Below y tan x pi 2 is basically y tanx shifted to the right by pi 2 That means that the entire graph including the asmpytotes move to the right by pi 2 units graph tanx 10 10 5 5 Above is y tanx graph tan x pi 2 10 10 5 5 Above is y tan x pi 2 If you focus on 0 0 in the first graph you will notice that in y tan x pi 2 it has shifted to the right by pi 2 units or See below tan x pi 2 cotx not cotx We cannot use the tangent difference identity as tan pi 2 doesn t exist
