Fill in the blanks to complete the verification. If a squared term is needed, type it as (sin x) sq. (Fill in the blank does not allow for exponents Note: Type x in place of theta for any answers where you need the angle/variable. cos (0+270) = sin 0 E Proof: 1. cos(8+270) 2. Use the sum/difference identity: cos sin 8 3. Replace the values that you know in the function. (i.e. replace any specific angle values) cos sin 4. Simplify:
