Question

learn the values of all the trignometric values of:
0 degree 30 degree 45 degree 60 degree and 90 degree​

Answer 1

inverse

sin 0 = 0 cosec0=infinity

sin 30 = 1/2 cosec30=2

sin 45=1/√2 cosec45=√2

sin 60=√3/2 cosec60 =2/√3

sin90 =1 cosec90=1

reverse inverse

cos 0=1 sec0=0

cos30=√3/2 sec30=2/√3

cos45= 1/√2 sec45=√2

cos60=1/2 sec60=2

cos90=0 sec90=infinity
