Question 1/2 Medium Mathematics Trigonometric Functions Trigonometric functions and their properties Class 11 Level 72

\(\tan \theta \cdot \cot \theta\) का मान क्या है, जब दोनों परिभाषित हों?

What is the value of \(\tan \theta \cdot \cot \theta\), when both are defined?

Explanation opens after your attempt
Correct Answer

C. (1)

Step 1

Concept

\( \cot \theta=\frac{1}{\tan \theta}\), so the product is (1). In exams reciprocal formulas save time.

Step 2

Why this answer is correct

The correct answer is C. (1). \( \cot \theta=\frac{1}{\tan \theta}\), so the product is (1). In exams reciprocal formulas save time.

Step 3

Exam Tip

\(\cot \theta=\frac{1}{\tan \theta}\), इसलिए गुणनफल (1) है। परीक्षा में reciprocal formulas से समय बचता है।

Question 2/2 Easy Mathematics Trigonometric Functions Trigonometric functions and their properties Class 11 Level 70

(\tan\left\(\frac{\pi}{2}-\theta\right\)) किसके बराबर होता है?

What is (\tan\left\(\frac{\pi}{2}-\theta\right\)) equal to?

Explanation opens after your attempt
Correct Answer

C. \(\cot \theta\)

Step 1

Concept

(\tan\left\(\frac{\pi}{2}-\theta\right\)=\cot \theta). The cofunction of \(\tan \theta\) is \(\cot \theta\).

Step 2

Why this answer is correct

The correct answer is C. \(\cot \theta\). (\tan\left\(\frac{\pi}{2}-\theta\right\)=\cot \theta). The cofunction of \(\tan \theta\) is \(\cot \theta\).

Step 3

Exam Tip

(\tan\left\(\frac{\pi}{2}-\theta\right\)=\cot \theta) होता है। \(\tan \theta\) का सह-फलन \(\cot \theta\) है।
