Solve each of the trigonometric equations and obtain the value of the unknown. a) 2 cos x-1= 0

b) cos(2+1)=0

c) sen2x = senx + 3

d) 3csc x = 3sen x

e) csc2 x = 1 + cot2 x

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

slope is 35 and 20 miles is the y-intercept.
