In trigonometry formulas, we will learn all the basic formulas based on trigonometry ratios (sin,cos, tan) and identities as per Class 10, 11 and 12 syllabi. Also, find the downloadable PDF of trigonometric formulas at BYJU'S.
1/sin x = cosec x; 1/cos x = sec x; 1/tan x = cot x; Steps to Create a Trigonometry Table Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. Step 2: Determine the value of sin
The function y = sin x is an odd function, because; sin (-x) = -sin x. Sine function Period and Amplitude. From the above, we can observe that if x increases (or decreases) by an integral multiple of 2π, the sine function values do not change. Thus, sin (2nπ + x) = sin x, n ∈ Z
Given, sin 300 ° We know that . sin α-β = sin α cos β-cos α sin β. Now by substituting the value of α = 360 ° and β = 60 ° in the trigonometric identity we get. sin 360 °-60 ° = sin 360 ° cos 60 °-cos 360 ° sin 60 ° ⇒ sin 360 °-60 ° = 0-1 × 3 2 ∵ cos 360 ° = 1, sin 360 ° = 0, cos 60 ° = 1 2 and sin 60 ° = 3 2 ⇒ sin ...
Here, 90° is multiplied by 4, i.e. an even number, so cos will not change in the result. Also, 360° – θ comes in the fourth quadrant, where cos is always positive. So, cos(360° – θ) = cos θ. Cos 360 + Theta. The value of cos 360 + theta can be calculated as given below: The value of the expression cos 360 + theta, i.e. cos(360° + θ).
In the same way, we can find the trigonometric ratio values for angles beyond 90 degrees, such as 180°, 270° and 360°. Unit Circle. The concept of unit circle helps us to measure the angles of cos, sin and tan directly since the centre of the circle is located at the origin and radius is 1. Consider theta be an angle then,
Tan θ=Sin θ/Cos θ. Therefore, Tan 0 0 =Sin 0 0 /Cos 0 0 =0. Tan 30 0 =Sin 30 0 /Cos 30 0 = √3/2. Tan 45 0 =Sin 45 0 /Cos 45 0 =1. Tan 60 0 =Sin 60 0 /Cos 60 0 =√3. Tan 90 0 =Sin 90 0 /Cos 90 0 =Undefined. We learned about sin theta 0 degrees value along with other degree values here, this far. Also, derived the value for cos degree and ...
The angles are calculated with respect to sin, cos and tan functions. Usually, the degrees are considered as 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°. Here, we will discuss the value for sin 30 degrees and how to derive the sin 30 value using other degrees or radians. Sine 30 Degrees Value. The exact value of sin 30 degrees is ½.
When we find sin cos and tan values for a triangle, we usually consider these angles: 0°, 30°, 45°, 60° and 90°. It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios (sine, cosine, tangent, cotangent, secant and cosecant).
