What is sin theta into SEC Theta?

What is sin theta into SEC Theta?

sin(θ)sec(θ)=tan(θ)

What is the relation between sin theta and SEC Theta?

There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).

What is the formula of sin theta?

The sine of an angle of a right-angled triangle is the ratio of its perpendicular (that is opposite to the angle) to the hypotenuse. The sin formula is given as: sin θ = Perpendicular / Hypotenuse.

How do you change sin into SEC?

Start with the ratio identity involving sine, cosine, and tangent, and multiply each side by cosine to get the sine alone on the left. Replace cosine with its reciprocal function. Solve the Pythagorean identity tan2θ + 1 = sec2θ for secant.

What is the formula for sin theta?

How do you solve sin Theta?

To solve, isolate the sine of the unknown angle by multiplying both sides of the equation by the length of angle theta’s opposite side. For example: sin A/a = sin B/b becomes (b * sin A)/a = sin B. In a calculator, given side a = 5, side b = 7, and angle A = 45 degrees, this is seen as SIN^-1((7*SIN(45))/5).

What is the formula for sin 2 theta?

Sin 2 theta is the sine of the angle which is double the value of theta. A formula to calculate sin 2 theta is: Sin 2 theta = 2 x (sin theta) x (cos theta)

What is sin Theta the reciprocal of?

The reciprocal sine function is cosecant, csc (theta)=1/sin (theta). The reciprocal tangent function is cotangent, expressed two ways: cot (theta)=1/tan (theta) or cot (theta)=cos (theta)/sin (theta). identities the unit circle reciprocal identities the Pythagorean identities.

What is the formula for cos Theta?

The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse, where θ is one of the acute angles. The cosine formula is as follows: (Cos Theta = frac{Adjacent}{Hypotenuse})
