Question

3.
If y=tan , the value of 0= 60° and error in
measurement of angle is 1.8º. Find the value of
Ay.
(a) 0.126 (b) 1.25 (c) 0.014 (d) 0.0126​

Answer 1

Answer:

(a) 0.126

Explanation:

1. firstly we will convert 0° into radian which will be π/100
2. We will do differentiation

• y=tan0
• ∆y/∆0= sec^2 '0' (1) (sec^0=4)
• ∆y = 4×∆0
• ∆y = 4×π/100
• ∆y =π/25
• ∆y = 0.126

{I have denoted thita with '0'}
