How are these done and what are some answers??? THE LITTLE O's ARE DEGREES?

Question

) Find the value of each expression to four significant digits. You may use a calculator for this portion. For e-h, angle measurements are in radians.

a) sin 142.5o = b) csc 224o = c) cos 300o12’ = d) sec 401o =

e) tan 6 = f) cot 7.28 = g) sec 5.1 = h) cot (-1.2) =

Answer 1

Hi,

Use your calculator to find these.

a) sin 142.5° = .6088

b) csc 224° = 1/sin 224° = -1.4396

c) cos 300° 12’ = .5030

d) sec 401° = 1/cos 401° = 1.3250

e) tan 6 = -.2910

f) cot 7.28 = 1/tan 7.28 = .6466

g) sec 5.1 = 1/cos 5.1 = 2.6457

h) cot (-1.2) = 1/tan -1.2 = -.3888

I hope that helps!! :-)
