Thank you to whoever takes a look at this question and answers it! I will give the first person to answer correctly ten points as soon as yahoo allows me to choose the best answer! :)-Evaluate the inverse trigonometric expresson. Give your answer to the nearest degree.(√3)/2 = 0.Looking in a trig table tells us that 0.......
1. Evaluate the inverse trigonometric expresson. Give your answer to the nearest degree. Cos -1 (√3/2)

Evaluate the inverse trigonometric expresson. Give your answer to the nearest degree. Cos -1 (√3/2)

(√3)/2 = 0.8660

Looking in a trig table tells us that 0.8660 = cos[30 degrees]

I take "cos -1 (√3/2)" to mean "arccos[√3/2]" which I choose to write as "cos^-1[√3/2]

so

cos^-1[√3/2] = 30 degrees = pi/6 radians
