Cos 225 Value

Cos 225 Value - cos 225 ∘ can be expressed as. cos 225 ∘ = cos ( 180 ∘ + 45 ∘) ⇒ cos ( 180 ∘ + 45 ∘) = cos 180 ∘ × cos 45 ∘ – sin 180 ∘ × sin 45 ∘ ; [ cos ( A + B) = cos ( A) × cos ( B) − sin ( A) × sin ( B)] Substituting the values of the above angles we get, cos 180 ∘ = - 1, cos 45 ∘ = 2 2, sin 180 ∘ = 0 and sin 45 ∘ = 2 2. Trigonometry Simplify cos 225 cos 225 cos 225 Apply the reference angle by finding the angle with equivalent trig values in the first quadrant Make the expression negative because cosine is negative in the third quadrant cos 45 cos 45 The exact value of cos 45 cos 45 is 2 2 2 2 2 2 2 2
