1. If Sin θ = 3/5, what will be the value of Cos Theta? Using Trigonometric identities: Cos2θ + Sin2θ = 1, so Cos2θ = 1- Sin2θ Cos2θ = 1 – (3/5)2 1– (9/25) = (25 – 9)/25 = 16/25 Cos θ = √(16/25) Cos θ = ⅘ So, cos theta is equal to ...
1. What is the Value of Cos 0? Cos 0° is equal to\[\sqrt \frac {4}{4}\]=1. The standard angles such as cos 0°, 30°, 45°, 60° and 90° are all possibly the positive roots of their fractional values. 2. How can we remember Cos Value?
r2=25cos2θ Graphs: The graphs are used to depict many pieces of information about the function. The graph is generally plotted in the plane using the table of values. The table of values is the value of the function at different point of the curve. Answer and Explanation: Here the ta...
Given that tan x = 2/5 and pi less than x less than 3pi/2, find the value for cos x. If \cos \theta = \frac{2}{3} and 270^\circ less than \theta less than 360^\circ, then determine the exact value of \frac{1}{\cot \theta}. Find the exa...
So, we can write cos 360 as cos (360×π180360×π180=cos2πcos2π So, we can write thatcos2πcos2π=1 Cos 360 value infractions Cos 360 value is the integer 1, so in fraction we can write it as 1/1 Cos 360 value inDecimals ...
