The most important part of this numerical is that we have to remember the values of $tan$ for different angles, as shown in the table below

Question: Given 15 cot A = 8, find sin A and sec A. In problems like these, make sure you know all the formulas mentioned in the notes

Question: Given a right triangle PQR, where m∠Q = 90°, PQ = 12 cm and PR = 13 cm, find the value of tan P - cot R.

We have already studied the basics of Trigonometry and the formulas of Trigonometry in the previous notes about Trigonometry. If you haven't read the notes, read it now

In this notes we'll cover topics about Trigonometry. We'll study about what is Trigonometry, why one should study Trigonometry and then about the basic formulae of Trigonometric Ratios. Trigonometry is the study of triangles. More specifically right angled triangles.
