Trigonometric Ratios and Functions

The video tutorial explains how to determine the six trigonometric ratios for angle A in a right triangle using the mnemonic 'soh cah toa'. It covers the calculation of sine, cosine, and tangent, and their reciprocal functions: cosecant, secant, and cotangent. The tutorial emphasizes understanding the relationships between the sides of the triangle and the angle to compute these ratios.

What mnemonic is used to remember the trigonometric ratios?

• Soh toa cah

• Sine cosine tangent

• Opposite adjacent hypotenuse
