You’re standing at the edge of a cliff, phone in hand, trying to measure the distance to the opposite side – no tape measure, no drone, just your brain. Now what? Trigonometry just became your ...

It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The shape ABCDEFGH is a cuboid. Length AB is 6 cm, length BG is 3 cm and length FG ...

Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...

The introduction of the transistor and then the microprocessor in the late 1960s and 1970s made it possible to build electronic calculators that could compute trigonometric functions directly. These ...

Anyone who’s taken classes in geometry, algebra, trigonometry or other advanced math forms has certainly encountered the graphing calculator before. These multi-function devices make incredibly ...
