3 sin square 45 degree + 2 cos square 60 degree
Added by Enrique T.
Step 1
sin 45 degrees = 1/√2 (using the special triangle or unit circle) cos 60 degrees = 1/2 (using the special triangle or unit circle) Now we can substitute these values into the equation: 3 sin^2 45 degrees + 2 cos^2 60 degrees = 3 (1/√2)^2 + 2 (1/2)^2 = Show more…
