WebCos θ = Adjacent side/Hypotenuse = AB/AC Tan θ = Opposite side/Adjacent side = BC/AB We can see clearly from the above … WebUse cosine, sine and tan to calculate angles and sides of right-angled triangles in a range of contexts.
WebPythagoras. Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides:. x 2 + y 2 = 1 2. But 1 2 is just 1, so:. x 2 + y 2 = 1 equation of the unit circle. Also, since x=cos and y=sin, we get: (cos(θ)) 2 + (sin(θ)) 2 = 1 a useful "identity" Important Angles: 30°, 45° and 60°.
