The constant e (known as Euler's constant) isn't used so much for trigonometry as it is for exponential functions. The constant e possesses the trait such that if we graph the curve
f(x) = e^x
Then the slope of the tangent line at x = 0 is equal to 1.
In more advanced courses, you'll learn that e actually does have a relationship with trigonometric functions, in the realm of complex numbers ( i = sqrt(-1)), given by the formula
e^(ix) = cos(x) + i sin(x)

e is an irrational value. its valu is 2.72 ............ logarithms and e functions are inverse.
