1A.) If angle A is 45 degrees and angle B is 60 degrees. Find cos(A)sin(B)

1B.) If angle A is 45 degrees and angle B is 60 degrees.Find sin(A)sin(B)

1C.) If angle A is 45 degrees and angle B is 60 degrees.Find sin(A)sin(B)

Solution

1A.) If angle A is 45 degrees and angle B is 60 degrees. Find cos(A)sin(B)

--- cosAsinB = cos45sin60 = (1/sqrt2)*sqrt3/2 = sqrt(3)/2sqrt(2)

1B.) If angle A is 45 degrees and angle B is 60 degrees.Find sin(A)sin(B)

---- sinAsinB = sin45*sin60 = (1/sqrt2)*(sqrt3/2) = sqrt(3)/2sqrt(2)

1C.) If angle A is 45 degrees and angle B is 60 degrees.Find sin(A)sin(B)

sin(A)sin(B) = sin45*sin60 = 1/sqrt2*sqrt3/2

= sqrt3/2sqrt2
