WebbA surd is said to be in its simplest form when the number under the root sign has no square factors. For example 72 can be reduced to 4 × 18 = 2 18. But 18 still has the factor 9, so we can simplify further: 2 18 = 2 9 × 2 = 2 × 3 2 = 6 2. We stop at this stage seeing that 2 has no square numbers as factors.

Webb4 aug. 2024 · θ can be in the first quadrant 0 ≤ θ ≤ 90 or the fourth quadrant 270 ≤ θ ≤ 360. If θ is in the first quadrant, then. sinθ = 5 13. cosθ = 12 13. tanθ = 5 12. Therefore, sin2θ = 2sinθcosθ = 2 × 5 13 × 12 13 = 120 169. cos2θ = cos2θ − sin2θ = (12 13)2 − ( 5 13)2 = 144 169 − 25 169 = 119 169.
