In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived ... but based on this post by math visualization guru Lucas) gives us the ...

Trigonometry is found all throughout geometry, as every straight-sided ... we’ll focus exclusively on the discovery and passage of sine, cosine, and tangent. The oldest record of the sine ...

I had flashbacks to high school geometry. Sine, cosine, tangent... remember those? “Yeah, this is all geometry,” Speck said. So, to figure out this problem, you should probably know that the ...

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

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 class Trigonometry: Sine, Cosine, and Tangent discusses the three basic ratios that are the basis for trigonometry. Trigonometry is based on the specific relationships between the sides and angles ...

The tangent is defined ... by dividing the sine function by the cosine function. Microsoft Excel simplifies the process by calculating the functions; however, some math conversions are required ...
