Hello from MrBillDoesMath!
Answer:
t = 135 is on example
Discussion:
Consider t = 135 (degrees)
sin(t) = + Sqrt (2)/2
cos(t) = - Sqrt(2)/2
tan(t) = -1
Visualization: 135 is in second quadrant where sin ("y component') is positive and cos ("x component") is negative. This implies that ratio ( or tan(t) ) is also negative.
Thank you,
MrB
