In order to find the values of trigonometrical functions for any angle in terms of those of positive acute angle, we have the following algorithm (from my textbook):ALGORITHMSTEP I: See whether the given angle a is positive or negative if it is negative, make it positive ...
Learn the cos 0 and the other trigonometric ratio values at BYJU'S. The cosine function of an angle is equal to the length of the adjacent side divided by the hypotenuse side.
Step 2:Use definitions to find the remaining trigonometric functions. sin(θ)=35 tan(θ)=34 csc(θ)=53 sec(θ)=54 cot(θ)=43 Example Problem 2: Finding the Values of Trigonometric Functions & their Reciprocals
Find the value of each trigonometric ratio. 1. cos x 2. sin C 3. tan Z 4. cos Z Find the EXACT values of the given trigonometric functions without using a calculator: (a) sin^{-1}(sin(5pi)) (b) cos(cos^{-1}(0.8)) Find the exact values of the given trigonom...
The value of tan 90 degrees is undefined. The tangent of an angle is equal to the ratio of sine and cosine of the same angle. Learn how to derive the exact value of tan 90 at BYJU’S.

DeepSeek doesn’t just learn, it evolves. Below are the innovations that are used by DeepSeek. Chain of Thought (CoT) Reasoning Chain of Thought is a very simple but effective prompt engineering technique that is used by DeepSeek. Here you can ask the model to ‘think out loud’ and br...
Cos 120°: ValueIn order to find the value of cos 120°, students need to draw a right-angled triangle (refer to the image below) and can use either of the two formulas i.e, cos (180° –θ) = – cosθ or cos (90° + θ) = – sinθ....
How to find cosecant Trigonometric Functions The three main trigonometric functions in trigonometry are sine, cosine, and tangent. However, there are three more trigonometric functions that, though they are less common than sine, cosine, and tangent, they are just as important and useful, and tho...
Sign: The "primary" functions are positive, and the "co" (complementary) functions are negative Scale: The hypotenuse (red) used by each function Swap: The other function in each Pythagorean triangle (sin ⇄ cos, tan ⇄ sec, cot ⇄ csc) Derivative: Multiply to find the derivativeTada...
