Sin 45.

A 45° angle creates an isosceles right triangle (45°-45°-90° triangle) in the first quadrant of the unit circle. In this triangle, the legs are equal, and the angles are 45°, 45°, and 90°. In a 45°-45°-90° triangle, the sides are related by the ratio: side length of the hypotenuse (H) = side length of one leg (L) × √2.sin (45° + θ) − cos (45° − θ) = ? (a) 2 sin θ. View Solution.
