WebAD2 = 3a2. Therefore, AD=a√3. Now in Triangle ADB, tan 60 = AD/BD = a√3/a = √3. Therefore, the exact value of tan 60 degrees is √3. We can also derive the values of Tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way. The values of the imporTant Functions of Sin can also be determined by the given method: Web30. °. ) Math Doubts. Trigonometry. Problems. sin ( θ + 60 °) − cos ( θ + 30 °) is a trigonometric expression and its value can be evaluated by simplifying it. The both trigonometric functions have angles which are sum of two angles so that the value of the trigonometric expression can be evaluated by using angle sum identities.

The solutions of cos θ = s m t h are defined up to addition of 360 ∘. So if you find the solutions of cos θ = 1 2 to be 60 ∘ and 300 ∘ (which is correct), you can still add to them any integer multiple of 360 ∘. Now if you have the equation cos 2 θ = 1 2, the solutions will look like. 2 θ = 60 ∘ or 300 ∘ + n ⋅ 360 ∘, tenny teamWebYou can use the formula sin(A−B) = sinA⋅ cosB −cosA⋅ sinB, so sin(90−θ) = sin90cosθ −cos90sinθ cosθ. You need to use the fact that ab = 0 (a = 0)∨ (b = 0). You divide by b and you lose the b = 0 predicate.
