In the question above, you accessed variables within the math module. Modules also define functions. For example, math provides the name sin for the sine function. Having imported math already, we can write math.sin(3) to compute the sine of 3. (Note that this sine function considers its argument to be in radians, not degrees. 180 degrees are equivalent to a radians.) Question 2.1.1. A 4-radian (45-degree) angle forms a right triangle with equal base and height, pictured below. If the hypotenuse (the radius of the circle in the picture) is 1, then the height is sin($). Compute that value using sin and pi from the math module. Give the result the name sine_of_pi_over_four . sin(e) = 4 cos() Source In [ ]: sine_of_pi_over_four = ... sine_of_pi_over_four In [ ]: grader.check("q211")
