If sin x = 0.3, find sec x?
***
cosx=√(1-sin^2x)≈√(1-0.3^2)≈√(1-0.9)≈√0.1≈0.316
secx=1/cosx≈3.162

Hi, there-- THE PROBLEM: If sin x = 0.3, find sec x? A SOLUTION: We know that sin x = 0.3. Use the trig identity to find the value of cos x. Substitute 0.3 for sin x. By definition, sec x = 1/cos x This irrational number is an exact answer for sec x. If you convert this to a decimal, it will be an approximation. Hope this helps!
