Trigonometric Ratios CBSE NCERT Solutions Chapter 8 Exercise 8.1 Question 2
2. In fig 8.13, find tan P – cot R.
Solution:
In
, using Pythagoras Theorem, we can say that
cm
tan P = (Opposite side to angle P) / (Adjacent side to angle P) = QR/PQ = 5/12 (1)
cot R = (Adjacent side to angle R) / (Opposite side to angle R) = QR / PQ = 5/12 (2)
From (1) and (2), we can say that
tan P – cot R =
= 0
