The period of the cosine function is 2π radians. That is, the value of cos(Θ) repeats every 2π radians. Therefore whatever value of the variable in the function argument causes the argument to change by an amount equal to 2π is the period of the function.
<span>The argument of cos(x/3) is x/3. What value of x makes x/3 = 2π </span>
<span>
x/3 = 2π </span>
<span>
x = 6π
</span>
<span>Therefore the period of y =cos(x/3) is 6π</span>
Series would be: 1,3,5......99
Here, a=1, d = 3-1 = 2, l = 99
l = a+(n-1)d
99 = 1+(n-1)2
98 = 2n-2
2n = 100
n = 50
Sum would be Sn = n/2 (a+l)
50/2 (1+99)
25(100) = 2500
So, your answer is 2500
Answer:
D. 100°
Step-by-step explanation:
A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.
50 + 30 = 80
180 - 80 = 100
