Trig function signs
WebMar 5, 2016 · In your setup, you start with A as origin (0,0). Anything on the left-hand side of this is a negative value. If you consider the triangle DCB and ignore rest. Then point D would become (0,0) in that setup and all values to the right-hand side would be positive and all values to the left of D would be negative. WebAn odd function is a function in which -f(x)=f(-x). It has symmetry about the origin. An even function is a function in which f(x)=f(-x) meaning that reflecting the graph across the y-axis will yield the same graph. Of the 6 trigonometric functions, sine, tangent, cosecant, and cotangent are odd functions. Cosine and secant are even functions.

And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30.
