Answer:
LHS = tan Q + cot Q
= sin Q/cos Q + cos Q/sin Q
= sin² Q + cos²Q/cos Q. sin Q
= 1/sin Q. cos Q
= RHS
LHS = RHS
here, we used the identity :
tan A = sin A/cos A
cot A = cos A/sin A
sin²A+cos²A = 1

Step-by-step explanation:
LHS = tan Q + cot Q
= sin Q/cos Q + cos Q/sin Q
= sin² Q + cos²Q/cos Q. sin Q
= 1/sin Q. cos Q
= RHS
LHS = RHS
here, we used the identity :
tan A = sin A/cos A
cot A = cos A/sin A
sin²A+cos²A = 1
