FAQs on Tips & Tricks: Trigonometry Video Lecture - Quantitative Aptitude for SSC CGL

1. What are the basic trigonometric functions?
Ans. The basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan). These functions are used to relate the angles and side lengths of a right triangle.
2. How do I find the value of a trigonometric function using a calculator?
Ans. To find the value of a trigonometric function using a calculator, first make sure your calculator is set to the correct angle mode (either degrees or radians). Then, input the angle measure in the appropriate unit and press the corresponding function key (e.g., sin, cos, tan). The calculator will display the value of the trigonometric function.
3. What is the Pythagorean identity in trigonometry?
Ans. The Pythagorean identity in trigonometry is a fundamental equation that relates the three basic trigonometric functions: sin^2(x) + cos^2(x) = 1. This identity holds true for any angle x.
4. How do I solve trigonometric equations?
Ans. To solve trigonometric equations, first isolate the trigonometric function on one side of the equation. Then, use inverse trigonometric functions (such as arcsin, arccos, or arctan) to find the angle that satisfies the equation. Finally, check whether the angles obtained are within the desired range and apply any necessary restrictions.
5. Can trigonometry be used in real-life applications?
Ans. Yes, trigonometry is used in various real-life applications, such as architecture, engineering, physics, and navigation. It is particularly useful for measuring distances, angles, and heights, as well as analyzing periodic phenomena and waveforms.
