Jul 16, 2015 · Solve triangle, knowing A = 43, a = 12.2, b = 14 Anser: B = 51.30 Apply the trig identity: sin a/A = sin B/b Find angle B: sin B/b = sin A/a --> sin B = (14 (0.68))/12.2 ==.78 --> - …

What is the exact value of the other primary trigonometric ratios of #tanTheta= (-5)/12# in quadrant II?

Apr 28, 2018 · Knowing the value of #x#, we can easily find the value of #y#.

Revolving around #x = -1# means doing the shell method makes this easier (you're revolving to make a shell, and you don't have to convert to #f (y)# functions).

(sec^2x+csc^2x)- (tan^2x+cos^2x) Simplify to one trig function?

This is standardised and usually calculated that way up. Sometimes the context of the question requires you to 'bend the rules' a bit but if you declare what you are doing the reader should …
