Trigonometry General Math Formula

For example if you are on the terrace of a tall building of known height and you see a post box on the other side of the road you can easily.

Trigonometry general math formula. There are six functions of an angle commonly used in trigonometry. Trigonometric formulas begin aligned sin alpha frac opposite hypotenuse cos alpha frac adjacent hypotenuse tan alpha frac opposite adjacent cot alpha frac adjacent opposite sec alpha frac hypotenuse adjacent csc alpha frac hypotenuse opposite end aligned. Their names and abbreviations are sine sin cosine cos tangent tan cotangent cot secant sec and cosecant csc. Trigonometry is the branch of mathematics that deals with the relationship between the sides and angles of a triangle.

Cot θ cot θ. Cosec θ 1 sin θ. Sin θ 1 cosec θ. We need to understand that trigonometric ratios would change for angles 90o θ and 270o θ and they will remain same for 180o θ and 360o θ.

Tan θ 1 cot θ. These six trigonometric functions in relation to a right triangle are displayed in the figure. There are many interesting applications of trigonometry that one can try out in their day to day lives. Trignometry resources video tutorials interactive lessons and free calculators.

With the height and base side of the right triangle given we can find out the sine cosine tangent secant cosecant and cotangent values using trigonometric formulas. Cot θ 1 tan θ. Cot 90o θ cos θ. All these are taken from a right angled triangle.

Let s see what happens when we add or subtract θ from 90o θ and 270o θ. Trigonometry the branch of mathematics concerned with specific functions of angles and their application to calculations. Sec θ sec θ.
