The six trig ratios for pi%2F4 are

sin%28pi%2F4%29%22%22=%22%22sqrt%282%29%2F2
cos%28pi%2F4%29%22%22=%22%22sqrt%282%29%2F2
tan%28pi%2F4%29%22%22=%22%221
sec%28pi%2F4%29%22%22=%22%22sqrt%282%29
csc%28pi%2F4%29%22%22=%22%22sqrt%282%29
cot%28pi%2F4%29%22%22=%22%221

5pi%2F4 is in QIII because:

pi%22%22%3C%22%221.25pi%22%22=%22%225pi%2F4%22%22%3C%22%221.5pi%22%22=%22%223pi%2F2

In QIII, only the tangent and cotangent are positive, others negative, so:

sin%285pi%2F4%29%22%22=%22%22-sqrt%282%29%2F2
cos%285pi%2F4%29%22%22=%22%22-sqrt%282%29%2F2
tan%285pi%2F4%29%22%22=%22%221
sec%285pi%2F4%29%22%22=%22%22-sqrt%282%29
csc%285pi%2F4%29%22%22=%22%22-sqrt%282%29
cot%285pi%2F4%29%22%22=%22%221
