Resumen del Recurso

Pregunta Respuesta
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)?
