What is the value of cot 90 degree minus theta?

The value of cot 90 minus theta can be written as cot(90° – θ) and its value is tan θ. Therefore, cot(90° – θ) = tan θ.

What is sin 90 minus theta and sin 90 theta?

Sin (90 – Theta) is equal to Cos Theta. Sin (90 – θ) = Cos θ

Why is sin (- theta )=- sin theta?

As we know, the angle (-x) lies in the 4th quadrant of a graph, and sine is negative in this quadrant. Hence, this shows that sin(-x) = -sin(x). What is sin theta? Sin theta of a right-angled triangle is equal to the ratio of the length of the opposite side to the length of the hypotenuse.

What is the formula of sin2A?

The general formula of sin2A is, sin2A = 2 sin A cos A. Using sin²A + cos²A = 1, we get sin A = √(1 - cos²A). Substituting this in the given formula, sin2A = 2 √(1 - cos²A) cos A. This formula is in the terms of cos or cosine function only.

What is the value of cos of minus theta?

Cos (-theta)=cos (theta). these answer is based on trigonometry ratio tables.

How do you find cos 90 Theta?

cos (90° + θ) = - sin θ.

What is the value of tan 90 Theta?

What is the exact value of tan 90? The exact value of tan 90 is infinity or undefined.

What is sin a minus Sin B?

The Sin A - Sin B difference to product formula in trigonometry for angles A and B is given as, Sin A - Sin B = 2 cos ½ (A + B) sin ½ (A - B) Here, A and B are angles, and (A + B) and (A - B) are their compound angles.

What is sinA cosB?

Sin a cos b is a trigonometric identity used to solve various problems in trigonometry. Sin a cos b is equal to half the sum of sine of the sum of angles a and b, and sine of difference of angles a and b.

What is cot minus theta?

cot (- 90)° = - tan 90°; since we know cot (- θ) = - tan θ

What is the value of sin 270 degree minus theta?

We know the trigonometric identity sin(270∘+θ)=−cosθ. Hence, the sine of 270 degrees is -1. We know the trigonometric identity cos(270∘+θ)=sinθ. Hence, the cosine of 270 degrees is 0.

What is cos 270 minus theta?

cos (270° - θ) = cos [180° + 90° - θ] = cos [180° + (90° - θ)] = - cos (90° - θ), [since cos (180° + θ) = - cos θ] Therefore, cos (270° - θ) = - sin θ, [since cos (90° - θ) = sin θ] tan (270° - θ) = tan [180° + 90° - θ]

What is the value of cos 180 degree minus theta?

The value of cos 180 is equal to -1.

What is sin2A sin2B sin2c?

sin2A+sin2B+sin2c= 4sinA.
