1 + tan 2 θ = sec 2 θ 1 + tan 2 θ = sec 2 θ. Table 1. The second and third identities can be obtained by manipulating the first. The identity 1 + cot 2 θ = csc 2 θ 1 + cot 2 θ = csc 2 θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot 2 θ = csc 2 θ 1 + cot 2 θ = csc 2 θ.
a2 c2 + b2 c2 = c2 c2. This can be simplified to: (a c)2 + (b c)2 = 1. a/c is Opposite / Hypotenuse, which is sin (θ) b/c is Adjacent / Hypotenuse, which is cos (θ) So (a/c) 2 + (b/c) 2 = 1 can also be written: sin 2 θ + cos 2 θ = 1. Note: sin2 θ means to find the sine of θ, then square the result, but.

Here, we show you a step-by-step solved example of trigonometric identities. This solution was automatically generated by our smart calculator: Starting from the left-hand side (LHS) of the identity. Applying the secant identity: $\displaystyle\sec\left (\theta\right)=\frac {1} {\cos\left (\theta\right)}$.
