By considering \(1^{\prime}=0.0175\), the approximate value of \(\cot 45^{\circ} 2^{\prime}\) is
- A \(1.07\)
- B \(0.965\)
- C \(1.035\)
- D \(0.93\)
Answer & Solution
Correct Answer
(D) \(0.93\)
Step-by-step Solution
Detailed explanation
Let \(f(x)=\cot x\) Since \(1^{\prime}=0.0175 \Rightarrow 2^{\prime}=0.035\) Now, \(f^{\prime}(x)=-\operatorname{cosec}^2 x\) By approximation, we get…
