Chapter 27 Trigonometrical Ratios of Standard Angles
Exercise 27.3 | Q 2.1

Use the given figure to find:
(i) tanθ°
(ii) θ°
(iii) sin²θ° - cos²θ°(iv) Use sin θ° to find the value of x.

Find the magnitude of angle A, if 2 sin A cos A - cos A - 2 sin A + 1 = 0

If 2 cos (A + B) = 2 sin (A - B) = 1;
find the values of A and B.

If A = 30°, verify that cos2θ = `(1 - tan^2 θ)/(1 + tan^2 θ)` = cos⁴θ - sin⁴θ = 2cos²θ - 1 - 2sin²θ

If θ = 30°, verify that: sin 3θ = 4sinθ . sin(60° - θ) sin(60° + θ)

If θ = 30°, verify that: 1 - sin 2θ = (sinθ - cosθ)²

Evaluate the following: cot20° cot40° cot45° cot50° cot70°

Evaluate the following: tan(78° + θ) + cosec(42° + θ) - cot(12° - θ) - sec(48° - θ)

Evaluate the following: `(3sin37°)/(cos53°) - (5"cosec"39°)/(sec51°) + (4tan23° tan37° tan67° tan53°)/(cos17° cos67° "cosec"73° "cosec"23°)`

If sin(θ - 15°) = cos(θ - 25°), find the value of θ if (θ-15°) and (θ - 25°) are acute angles.
