| Question | Answer |
| How do you calculate sin? | opposite ------------------ hyptoenuse |
| How do you calculate cos? | adjacent -------------- hypotenuse |
| How do you calculate tan? | opposite ------------- adjacent |
| How do you know weather to use sin, cos or tan? | The hypotenuse is always the line opposite the right angle. Adjacent is always the line next to the angle. Opposite is always the line opposite the angle. SOH CAH TOA |
| How do you calculate sin (side)? | sin θ = opposite / hypotenuse sin (angle) = x / hypotenuse x = sin (angle) x hypotenuse |
| How do you calculate sin (angle)? | sin θ = opposite / hypotenuse θ = sin-1 (opposite / hypotenuse) |
| How do you calculate cos (side)? | cos θ = adjacent / hypotenuse cos (angle) = x / hypotenuse x = sin (angle) x hypotenuse |
| How do you calculate cos (angle)? | cos θ = adjacent / hypotenuse θ = cos -1 (adjacent / hypotenuse) |
| How do you calculate tan (side)? | tan θ = opposite / adjacent tan (angle) = x / adjacent x = tan (angle) x adjacent |
| How do you calculate tan (angle)? |
