What does COSX 1 mean?

1 Expert Answer 1) In the unit circle the x represent the cosine of the function and the y represent the sine of the trigonometric function. 2) Looking at the unit circle I noticed that cos(x) =1, corresponds to 360°. in other words cos (360º) =1, the answer is x=360º or x=2π radians.

How do you write cos?

In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as ‘cos’. Often remembered as “CAH” – meaning Cosine is Adjacent over Hypotenuse….Cosine (cos) function – Trigonometry.

What does Cos divided by Sin equal?

The sine, cosine and cotangent functions are defined in trigonometric mathematics at an angle in the ratio form of the sides of a right triangle. It is possible to divide the cosine by sine mathematically and their quotient is equal to the cotangent . Hence, it is called the cosine by sine quotient identity.

What is the integral of sin 2?

The integral of sin^2 is one-half of x, minus one-eighth of the sine of 4x, plus a constant. Using mathematical notation, the integral of sine squared can be written as sin^2 x dx = 1/2 * x – 1/8 * sin(4x) + C. Sine squared can be integrated using the half-angle integration technique.

What is the inverse cosine of 1?

As you can see below, the inverse cos-1 (1) is 0° or, in radian measure, 0. ‘1’ represents the maximum value of the cosine function. It happens at 0 and then again at 2Π, 4Π, 6Π etc..

What does inverse sin equal?
