Question
The following table shows the monthly rainfall in a
city for the first six months of the year: What is the percentage increase in rainfall from January to June?Solution
ATQ, Percentage increase = [(June rainfall - January rainfall) / January rainfall] * 100 Percentage increase = [(30 - 10) / 10] × 100 = 200%
- If sin A = √3/2, then what will be the value of sec² A?
Simplify the following trigonometric expression:
14 tan 25° cot 65° − 6 cos 39° sec 51°What is the simplified value of the given expression?
4(sin² 20° + sin² 70°) + 2sin 30° - (2sec 60° + cot 45°)
If cos 2A = 7, then find cos A
If sec x + tan x = 11 then find secx?
If √3 tan 2θ – 3 = 0, then find the value of tanθ secθ – cosθ where 0 < θ < 90°
If cosB = sin(1.5B - 15°), then find the measure of 'B'.
