Summation/difference cos ⁡ ( θ ± ϕ) = cos ⁡ θ cos ⁡ ϕ ∓ sin ⁡ θ sin ⁡ ϕ {\\displaystyle\\cos (\\theta\\pm\\phi )=\\cos\\theta\\cos\\phi

Half-angle cos ⁡ θ 2 = ± 1+cos ⁡ θ 2 {\\displaystyle\\cos {\\frac {\\theta } {2}}=\\pm {\\sqrt {\\frac {1+\\cos\\theta } {2}}}} sin ⁡ θ 2 =

What is the exact value of Cos 135?

cos135° = cos (90+45)° 45° is the reference angle. cos 45° = sqrt (2)/2, cos135° = – sqrt (2)/2 since cos theta is negative in Quad II. *** For Quad II reference angles take 180 – x ***. I took 180 – 135 = 45. It was the rest of the angle down to 180 that I wanted NOT the c in 90 + c above.

How would you write 135 as a fraction?

Write down the number as a fraction of one: 0.135 = 0.135 1

Multiply both top and bottom by 10 for every number after the decimal point: As we have 3 numbers after the decimal point,we multiply both numerator and

Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them.

What is the exact value of Cos 135 degrees?

Using trigonometric identities, we can write sin 135° in terms of cos 135° as, sin(135°) = √(1-cos²(135°)). Here, the value of cos 135° is equal to −(1/√2) . Here, the value of cos 135° is equal to −(1/√2) .
