Question

cot x =3/4 ,x lies in fourth quadrant. find other trigonometric functions​

Answer 1

Answer:

cotx=43

⇒tanx=cotx1=34

Now ∵1+tan2x=sec2x

⟹sec2x=1+916⟹sec2x=925

secx=±35

Since x lies in third quadrant, the value of secx will be negative.

∴secx=−35

cosx=secx1=−53

tanx=cosxsinx⟹sinx=(34)×(−53)=−54

∴cscx=sin
