If f(2tanx/1 tan^2x)=(1 cos2x)(sec^2x 2tanx)/2 then f(4)= 308871 kijpsaelowxj

Cos2 (x) (1 tan2 (x)) = 1 cos 2 ( x) ( 1 tan 2 ( x)) = 1 Replace the cos2(x) cos 2 ( x) with 1−sin2 (x) 1 sin 2 ( x) based on the sin2(x)cos...

Sin π/2 value 398810-Sin π/2 value kijpsaelowxj

I hope you know that π/2 rads = 90 degrees This is the graph of y = sin(x) from x = 360 to 7 degrees Now if we consider sin(n × 90) w2 dx fr...
