Question

46 properties trignometry​

Answer 1

Answer:

• sin 0degree =0 sin 30degree=1/2 sin 45 degree=1/√2 sin 60degree=√3/2 sin 90degree=1

Explanation:

1. cos 0degree=1 cos 30degree=√3/2 cos 45degree=1/√2 cos 60degree=1/2 cos90degree=0 tan 0degree=0 tan 30degree=1/√3 tan 45degree=1 tan 60degree=√3 tan 90degree=not defined
