Under dryland farming situation which practice is most

tan 1˚ × tan 2˚× …………………….tan 88˚ × tan 89˚ = ?

If x = 4 cos A + 5 sin A snd y = 4 sin A – 5 cos A, then the value of x²+y² is :

Determined the simplified value of the given expression:(1 - sin² q) X (sec q + tan q) X (sec q - tan q) X cosec² q

What is the simplified value of the given expression?

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

If 9 sinx + 40 cosx = 41 then find tanx.

Find the slope of the equation : 12x + 4y = 28.

Solve for x in the interval [0, 2π]: 2 sin²x + 3 sinx - 2 = 0.

If (2sin A + cos A) = 3sin A, then find the value of cot A.
