WebHowever, if we extend Euler's formula e^ (iz)=cos (z) + i sin (z) to complex-valued z, then the answer is yes! We have e^ (i*i) = cos (i) + i sin (i) and e^ (i*-i) = cos (-i) + i sin (-i). Recall that cosine and sine are even and odd functions, in this order. Websin cos and tan are basically just functions that relate an angle with a ratio of two sides in a right triangle. Sin is equal to the side opposite the angle that you are conducting the …

Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.
