How do I find sec?

The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle. The secant ratio is the reciprocal of the cosine ratio.

How do you find the secant function?

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

What is cosecant function?

The cosecant function is the relationship between the hypotenuse and the opposite side in a right triangle. We know that cscθ=hypotenuseopposite side ⁡ θ = hypotenuse opposite side . The numerator always is larger than the denominator as the hypotenuse is the longest side. Thus, the cosecant function is greater than 1.

Which of the following is an expression for sin Pi 2?

The exact value of sin(π2) sin ( π 2 ) is 1 .

How is a circle 2 pi?

Originally Answered: Why are there 2\pi radians in a circle? Because the length of the circumference of a circle is exactly 2*pi times the radius and by definition 1 radian is the angle subtended by a portion of the circumference equal in length to the radius. To 1 radia “goes into” the total circumference 2*pi times.
