Arctan (x) =θ = Arctangent. Find the Value Using the Unit Circle sec ( (7pi)/6) sec( 7π 6) sec ( 7 π 6) Find the value using the definition of secant. 866, 0. 866, -0. Make the expression negative because secant is negative in the third quadrant. Now look up in tables, or derive from the unit circle that sin (pi/6) = 1/2 and sin (pi/3) = sqrt (3)/2, such. Therefore, it's a correct answer to a problem. Example 2: Find the value of tan 7pi/3 if cot 7pi/3 is 0. To write as a fraction. Linear equation.

Jonathan and his sister Jennifer have a combined age of 48. Hence to plot (2,(7pi)/6) , one should plot point (-sqrt3,-1). -260 degree. Therefore, pi is equal to 180 degrees. . flex fuel e85 near me
