Question 751386: is there a shortcut to solve sin(x+45) or do I need to just apply sin(a+b)?

No. Actually, the formula for sin(a+b) IS the shortcut. For a quick reference see the Angle Sum and Difference Identities in http://en.wikipedia.org/wiki/Angle_sum_formula#Angle_sum_and_difference_identities
