Final Answer
true
Step-by-step Solution
Problem to solve:
$\sec\left(x\right)=\frac{\sin\left(2x\right)}{\sin\left(x\right)}-\frac{\cos\left(2x\right)}{\cos\left(x\right)}$
Specify the solving method
1
Starting from the left-hand side (LHS) of the identity
$\sec\left(x\right)$
2
Since the expression on the left of the equality is too simple, it's not clear how we can proceed to prove the identity from there. Although we know that the identity is true
true
