Evaluate the following: sin 0 ° sin 35 ° sin 55 ° sin 75 ° cos 22 ° cos 64 ° cos 58 ° cos 90 ° - Mathematics

Evaluate the following: `(sin0° sin35° sin55° sin75°)/(cos22° cos64° cos58° cos90°)`

Sum

`(sin0° sin35° sin55° sin75°)/(cos22° cos64° cos58° cos90°)`

= `(0 xx sin35° sin55° sin75°)/(cos22° cos64° cos68° xx 0)`
= 0.

Exercise 27.3 | Q 5.07

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

Solve for x : 2 cos (3x − 15°) = 1

Solve for 'θ': `sin θ/(3)` = 1

Solve for 'θ': cot²(θ - 5)° = 3

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

If `sqrt(3)` sec 2θ = 2 and θ< 90°, find the value of

cos 3θ
