Question
Which is not a part of 'Serve Safe'
initiative?Solution
The correct answer is D
What is the simplified value of the given expression?
4(sin² 20° + sin² 70°) + 2sin 30° - (2sec 60° + cot 45°)
Find the value of `1/2`  cosec 10  - `2/(cosec 70)`  ?
What is the value of sin(B – C) cos(A – D) + sin(A – B) cos(C – D) + sin(C – A) cos(B – D)?

- If sin(A + B) = 1/2 and cos(A + 2B) = √3/2, where 0° < A, B < 90°, then find the value of tan(2A).
If SecA + TanA = 2√2 + 3, then find the value of Sin A + Cos A
- Find the simplified value of the expression:sin 2 45 o  + sin 2 60 o  - (1/3) X tan 2 60 o
If sec A + tan A = (5/2) and sec A - tan A = (2/5), find the value of cos A.
cos A (sec A – cos A) (cot A + tan A) = ?
If X = 15°, find the value of:
sin²(4X) + cos²(3X) - tan²(2X)
