Step 4: Determine the value of tan. The tan is equal to sin divided by cos. tan = sin/cos. To determine the value of tan at 0° divide the value of sin at 0° by the value of cos at 0°. See the example below. tan 0°= 0/1 = 0. Similarly, the table would be. Angles (In Degrees) 0°. 30°.
The six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.

Law of Cosines in Trigonometry. The law of cosine or cosine rule in trigonometry is a relation between the side and the angles of a triangle. Suppose a triangle with sides a, b, and c and with angles A, B, and C are taken, the cosine rule will be as follows. According to cos law, the side “c” will be: c2 = a2 + b2 − 2ab cos (C) It is ...

We know that the exact value of cos 0 degrees is 1. So, cos 180 degree is - (cos 0) which is equal to - (1) Therefore, the value of cos 180 degrees = -1. It is also represented in terms of radians. So, value of cos pi = -1. There are some other alternative methods to find the value of cos 180°. To find out the value, some degree values of sine ...
You know that. Can you predict what the decimal expansion of are, without actually doing the long division? If so, how? [Hint: Study the remainders while finding the value of carefully.] Q. How do you find the values of θ given tanθ=1 ? Q. How do you find the values of sin2θ and cos2θ when cosθ= 12 13 ?
Find the value of cos 3 π 2. We know that . cos α + β = cos α cos β-sin α sin β. Now by substituting the value of α = π and β = π 2 in the trigonometric identity we get. cos π + π 2 = cos π cos π 2-sin π sin π 2 ⇒ cos π + π 2 = 0-0 ∵ cos π 2 = 0, sin π 2 = 1, cos π =-1 and sin π = 0 ⇒ cos 3 π 2 = 0. Hence the value ...
Mar 1, 2019 · If n is a odd number then its value is 0. if n is even number then its value is either 1 or -1. Step-by-step explanation: Given: put n = 0. we have, put n = 1. we have, put n = 2. we have, put n = 3. we have, put n = 4. we have, So, Value of depends on value of n. If n is a odd number then its value is 0. if n is even number then its value is ...
