Mar 2, 2022 ... cosx/sinx = (-1/2)/(1/2)sqr3 = (-1/2)(2/sqr3) = -1/sqr3 =-sqr3/3. cosx/sinx = -(1/3)sqr3 = about (-1/3)(1.732) = -1.732/3 = -0.577. or. cosx ... The period of the cos(x) cos ( x ) function is 2π 2 π so values will repeat every 2π 2 π radians in both directions. Find the values of other five trigonometric functions in Exercises 1 to 5: 1) cos x = -1/2, x lies in third quadrant.Hence the required values are sin x ...
