Question

cosec- sin o) (sec o - cos ) (tano
+coto) = 1​

Answer 1

Answer:

LHS=RHS

Step-by-step explanation:

solve LHS

(1/sin-sin)(1/cos-cos)(tan+1/tan)               [{cosec=1/sin}{sec=1/cos}{{cot=1/tan}                

(1-sin²/sin)(1-cos²/cos)(tan²+1/tan)

(cos²/sin)(sin²/cos²)(sec²/tan)

(cos/1)(sin/1)(1/cos²×cos/sin)

=1

∴LHS=RHS hence proved
