Test Status Code Input and Output
1   Pass
filetext = fileread('TANGENT.m'); assert(isempty(strfind(filetext, 'tan')),'tan() forbidden')

2   Pass
x = 0; y_correct = 0; assert(abs(TANGENT(x)-y_correct)<0.01)

y = 0

3   Pass
x = pi/4; y_correct = 1; assert(abs(TANGENT(x)-y_correct)<0.01)

y = 1.0000

4   Pass
x = -pi/4; y_correct = -1; assert(abs(TANGENT(x)-y_correct)<0.01)

y = -1.0000
