Question

10. If sino - coseco=0, then tano=?
a) 45°
b) 180°
c) 60°
d) 90°​

Answer 1

Step-by-step explanation:

sin(0)-cosec(0)=0

sin(0)=cosec(0)

sin^2(0)=1

sin(0)=1

theta=90

now tan(0)

tan(90)=n.d

as your que is wrong tan is not a angle its a ratio

Answer 2

hey buddy this is your answer

sinθ - cosecθ=0

it is only possible for the value of θ as 45 degrees

then tanθ=tan45=1

hence answer is (a) 45°
