0Angle. 0 30 45 . 60 . 90
Put 0. 1 . 2. 3 . 4
Diviede all by 4
0/4 . 1/4 . 2/4. 3/4. 4/4 take square root of all
0. 1/2. 1/√2. √3/2. 1
Then sin x= 0 . 1/2 . 1/√2. √3/2. 1
Cosx have opposite value of sinx so
Cosx = . 1. √3/2 . 1/√2 1/2 . 0
Tanx = sinx/Cosx so
Tanx= . 0 . 1/√3 . 1 . √3 notdefin
CosecX= 1/sinX
CosecX= not define. 2 √2 . 2/√3. 1
Secx is opposite of cosecx
SecX= 1. 2/√3. √2. 2. Not define
Cotx=. Cosx/SinX
CotX= . Not define √3. 1 . 1/√3. 0
This is value of 0' 30' . 45' 60'. 90' .Respectively in each case..
