## What are the 6 trig functions?

There are six main trigonometric functions:Sine (sin)Cosine (cos)Tangent (tan)Secant (sec)Cosecant (csc)Cotangent (cot).

## How do you find the 6 trigonometric ratios?

To evaluate the six trigonometric functions of 225 degrees using the unit circle, follow these steps:Draw the picture. … Fill in the lengths of the legs and the hypotenuse. … Find the sine of the angle. … Find the cosine of the angle. … Find the tangent of the angle. … Find the cosecant of the angle.More items…

## What are the 3 trigonometric ratios?

There are three basic trigonometric ratios: sine , cosine , and tangent . Given a right triangle, you can find the sine (or cosine, or tangent) of either of the non- 90° angles. Example: Write expressions for the sine, cosine, and tangent of ∠A .

## How do you know what trig ratio to use?

There are three steps:Choose which trig ratio to use. – Choose either sin, cos, or tan by determining which side you know and which side you are looking for.Substitute. … Solve. … Step 1: Choose which trig ratio to use. … Step 2: Substitute. … Step 3: Solve. … Step 1: Choose the trig ratio to use. … Step 2: Substitute.More items…

## What is CSC of an angle?

The cosecant ( csc ) (\csc) (csc) The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

## What is a 45 degree triangle?

A 45 – 45 – 90 degree triangle (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of. Note that it’s the shape of half a square, cut along the square’s diagonal, and that it’s also an isosceles triangle (both legs have the same length).

## What are the six trigonometric functions of a right triangle?

For any right triangle, there are six trig ratios: Sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Here are the formulas for these six trig ratios: Given a triangle, you should be able to identify all 6 ratios for all the angles (except the right angle).

## What does SOH CAH TOA mean?

Sine equals Opposite over Hypotenusewebsite feedback. SOHCAHTOA. A way of remembering how to compute the sine, cosine, and tangent of an angle. SOH stands for Sine equals Opposite over Hypotenuse. CAH stands for Cosine equals Adjacent over Hypotenuse.

## How do you do right triangle trigonometry?

Right triangle: Find the measure of angle A , when given the opposite side and hypotenuse. From angle A , the sides opposite and hypotenuse are given. Therefore, use the sine trigonometric function. (Soh from SohCahToa) Write the equation and solve using the inverse key for sine.

## How do you solve an angle using trigonometry?

Find the angle of elevation of the plane from point A on the ground.Step 1 The two sides we know are Opposite (300) and Adjacent (400).Step 2 SOHCAHTOA tells us we must use Tangent.Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.Step 4 Find the angle from your calculator using tan-1
