What is sinx COSX equal to?
What is sinx COSX equal to?
The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .
What happens when sinx COSX?
From the unit circle we see that sin x and cos x can only have the same value in two places, in x = /4 and x = 5 /4 (45° and 225°). The equation sin x = cos x can also be solved by dividing through by cos x. If we put k = 0 and k = 1 we get the solutions /4 (45°) and /4 + = 5 /4 (45°+ 180°= 225°).
What is minimum value of sinx COSX?
-1
The minimum value of sinx is -1 and the minimum value of y is -√2.
What is the fundamental period of sinx COSX?
The period of sinx is π and cosx is π. The given function is an even function and sinx, cosx is complementary.
What is COSX?
The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y.
How do you solve sin a cos a?
Sine of angle is equal to the ratio of opposite side and hypotenuse whereas cosine of an angle is equal to ratio of adjacent side and hypotenuse.
- Sin θ = OppositesideHypotenuse.
- Cos θ = AdjacentSideHypotenuse.
What is sinx Siny?

What is the minimum value of sinA?
Ywhat is the minimum value of sinA.
What is the minimum and maximum value of sin theta?
Properties Of The Sine Graph Maximum value of sin θ is 1 when θ = 90 ˚. Minimum value of sin θ is –1 when θ = 270 ˚. So, the range of values of sin θ is –1 ≤ sin θ ≤ 1.
What is the period for sinx?
2π
The period of sinx is 2π, whereas period of sinx/2 is 4π.
What is the period of cos2x?
Period would be 2π2 or π .
What is the formula for SiNx and cosx?
cosx = sin(π 2 − x) sinx + cosx = sinx +sin(π 2 − x)
Can you write cos x as sin 0?
We can write cos (-x) = cos (0-x), such as the following identity may now be used: But cos 0 = 1 and sin 0 = 0. Therefore, the identity cos (-x) = cos x is verified. 25 insanely cool gadgets selling out quickly in 2021.
