Evaluate the following: sin22° cos44° - sin46° cos68°

Sum

sin22° cos44° - sin46° cos68°
= sin(90° - 68°) cos(90° - 46°) - sin46° cos68°
= cos68° sin46° - sin46° cos68°
= 0.

Chapter 27 Trigonometrical Ratios of Standard Angles
Exercise 27.3 | Q 2.6

If 4 sin² θ – 1 = 0 and angle θ is less than 90°, find the value of θ and hence the value of cos² θ + tan² θ.

If sin 3A = 1 and 0 < A < 90^°, find `tan^2A - (1)/(cos^2 "A")`

Solve for x : cos² 30° + sin² 2x = 1

Solve for 'θ': `sin θ/(3)` = 1

If θ = 30°, verify that: sin2θ = `(2tanθ)/(1 ++ tan^2θ)`

Evaluate the following: `((1 - cosθ)(1 + cosθ))/((1 - sinθ)(1 + sinθ)` if θ = 30°

Find the value 'x', if:

Evaluate the following: sec16° tan28° - cot62° cosec74°

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

Prove the following: sin²30° + cos²30° = `(1)/(2)sec60°`
