Question
(ii) Convert the products of sine A and cos C into the sum form of trigonometric functions of the triangle above.
Solution
I'm sorry, but you didn't provide a specific question or a triangle to refer to. However, I can tell you how to convert the product of sine and cosine into a sum of trigonometric functions in general.
The product-to-sum identities for sine and cosine are:
sin(A)cos(B) = 1/2[sin(A+B) + sin(A-B)] cos(A)sin(B) = 1/2[sin(A+B) - sin(A-B)]
So, if you have sin(A)cos(C), you can convert it into the sum form as follows:
sin(A)cos(C) = 1/2[sin(A+C) + sin(A-C)]
Please provide more specific details if you need help with a specific problem.
