Which of the following cube in the answer figure cannot

sin² 7 ° + sin² 8 ° + sin² 9 ° + sin² 10 ° + ……… + sin² 83 ° = ?

Find the value of the given expression.

3 × (sin 30° + cos 60°)

What is the simplified value of the given expression?

2(sin² 15° + sin² 75°) + 4sin 30° - (2sec 60° + cot 45°)

If tan² 45°- cos² 60° x sin 45° cos 45° cot 30°, then find the value of 'x'.

If cosec (2A + B) = 2 and cosec (A + B) = 1, find the value of (3A – B).

The Value of (sin38˚)/(cos52˚)+ (cos12˚)/(sin78˚)- 4cos²60˚ is

If tan θ + cot θ = 2 where 0 < θ < 90 ; find the value of tan³⁰ θ + cot ²⁹ θ.

If θ is a positive acute angle and cos² θ + cos⁴θ = 1, then the value of tan²θ + tan⁴θ is?
