The method for finding the tangent may .

This relies on trigonometry (and suppleness!) and the fact that if you view.

You are now ready to calculate tree heights. Hold the card at arms length in front of your . Determine which trig function to use. The hypotenuse and opposite side are part of the sine ratio.

A middle school demonstration of proportional reasoning. It is possible to watch with no soun but the calculations at the end make more sense with sound. Outstretch your arm and hold the pencil so that you can measure the height of the tree on the pencil with your thumb.

Instea you can use trigonometry to calculate the height of the object. Two locations on Mount Ruapehu were used in this video. The first location was in podocarp forest, th. The Woodland Education Centre - Woodland Restoration Project. By using the principles of trigonometry , the height of tall objects can be calculated from the angles measured.

The height of an object is calculated by measuring the distance from the object and the angle of elevation of the top of the object. The tangent of the angle is the object height divided by the . Since your measurements will be . Measure distance from operator to plumb point (C) - not from the operator to the base of the tree , i. The basic tool that we will use is similar triangles and trigonometry. This unit follows on from others that introduce students to sine, cosine and tangent.
