What is the simplified value of the given expression?
4(sinĀ² 20Ā° + sinĀ² 70Ā°) + 2sin 30Ā° - (2sec 60Ā° + cot 45Ā°)
Find the value ofĀ `1/2` Ā cosec 10Ā Ā -Ā `2/(cosec 70)` Ā ?
What is the value of sin(B ā C) cos(A ā D) + sin(A ā B) cos(C ā D) + sin(C ā A) cos(B ā D)?
- If sin(A + B) = 1/2 and cos(A + 2B) = ā3/2, where 0Ā° < A, B < 90Ā°, 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 Ā + sin 2 60 o Ā - (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 = 15Ā°, find the value of:
sinĀ²(4X) + cosĀ²(3X) - tanĀ²(2X)
