Evaluate the following: 2 sin 28 ° cos 62 ° + 3 cot 49 ° tan 41 ° - Mathematics

Evaluate the following: `(2sin28°)/(cos62°) + (3cot49°)/(tan41°)`

Sum

`(2sin28°)/(cos62°) + (3cot49°)/(tan41°)`

= `(2sin(90° - 62°))/(cos62°) + (3cot(90° - 41°))/(tan41°)`

= `(2cos62°)/(cos62°) + (3tan41°)/(tan41°)`

= 2 + 3
= 5.

Chapter 27 Trigonometrical Ratios of Standard Angles
Exercise 27.3 | Q 3.3

State for any acute angle θ whether sin θ increases or decreases as θ increases

If sin α + cosβ = 1 and α= 90°, find the value of 'β'.

If θ = 30°, verify that: tan2θ = `(2tanθ)/(1 - tan^2θ)`

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

Find the value of 'y' if `sqrt(3)` = 1.723.
Given your answer correct to 2 decimal places.
