Question: If 3 cot A = 4, check whether (1−tan²A)/(1+tan²A) = cos²A - sin²A. Consider the following triangle ABC, where angle B = 90°
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.
