Can sin theta be equal to cos theta?
However, in the extremely particular case that the opposite and adjacent sides are the same, sinθ and cosθ will be equal, because these functions measure the relationships between sides, and if these relationships are equal, the functions will be equal in value.
What is sin theta equal to cos?
Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse . No matter the size of the triangle, the values of sin(θ) and cos(θ) are the same for a given θ, as illustrated below.
Is sin theta is equal to cos theta for all values of theta?
False. For none value of theta, sin thete can be equal to cos theta.
How does sin relate to cosine?
The sine of an angle is equal to the cosine of its complementary angle, and the cosine of an angle is equal to the sine of its complementary angle.
What is sin over COS?
The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .

What is the relationship between Sinx and COSX?
We write this property algebraically as cos x = sin ( x + π 2 ) . So the functions sin x and cos x are very closely related to each other. Evenness and Oddness: Looking at the graph of sin x, we see that it has point symmetry at the origin, and, specifically, that it passes through the origin.
What is equal to cos theta?
The Cos θ = Adjacent / Hypotenuse.
What is cos over sin?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

How to solve for Theta with cos?
Solve for? cos (theta)=0. cos (θ) = 0 cos ( θ) = 0. Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. θ = arccos(0) θ = arccos ( 0) The exact value of arccos(0) arccos ( 0) is π 2 π 2. θ = π 2 θ = π 2. The cosine function is positive in the first and fourth quadrants.
What is the formula for cos Theta?
The cosine double angle formula is cos (2theta)=cos2 (theta) – sin2 (theta). Combining this formula with the Pythagorean Identity, cos2 (theta) + sin2 (theta)=1, two other forms appear: cos (2theta)=2cos2 (theta)-1 and cos (2theta)=1-2sin2 (theta). These can be used to find the power-reduction formulas, which reduce a second degree or higher
What is the value of Cos 2 theta?
cos (theta) can never equal 2 because that would mean that the leg is greater than the hypotenuse which isn’t possible. ( 2) does not exist. There is no solution for c o s θ = 2 since the value of y = c o s x function is on the interval [ − 1, 1]
What is the value of sin Theta?
The maximum value of sin theta is 1 and it corresponds to tge sin value for any angle theta (radians) = π/2 + 2kπ (k being any whole number) Sin (t) i defined as the ratio of length of opposite side to the hypotenuse it a right triangle . The maximum value of sint, is 1 or it doesn’t exceed 1 , because in a right angled triangle, hypotenuse
