A tangent to a circle at point P is a straight line that ... Finally, the point where the tangent crosses the \(x\)-axis will have a \(y\)-coordinate of 0. Substituting this value into the ...

Similarly, simple harmonic motion may be derived from the projection onto the axis of a circle of a point moving with constant speed on the circumference, as shown in the diagram below.

Step 1 - Go along the x-axis to see which number the circle is in line with - 3. Step 2 - Now see which number the circle is opposite to on the y-axis - 4. Step 3 - Write the numbers as ...
