WebbThe sum and difference of angle formulas are equations used in carrying out the addition and subtraction of trigonometric identities. Unlike normal arithmetic operations, addition and subtraction of trigonometric functions have a different approach. For example, cos (45° -15 °) is not the same as cos45 ° - cos15 °. WebbThe following are important trigonometric relationships: sin (A + B) = sinAcosB + cosAsinB cos (A + B) = cosAcosB - sinAsinB tan (A + B) = tanA + tanB 1 - tanAtanB To find sin (A - B), cos (A - B) and tan (A - B), just change the + signs in the above identities to - signs and vice-versa: sin (A - B) = sinAcosB - cosAsinB
