Hi guys! This video discusses how to find the trigonometric ratios for all angles using the rectangular coordinate system. Basically, we can have an angle in standard position in xy plane where the terminal side can be located in four quadrants. We can have positive and negative angle by rotating the terminal side counterclockwise and clockwise, respectively. The terminal side will have a point P with x and y coordinate. The sign of all trigonometric functions are considered depending on the quadrants of angle it is located at. We use the concept of coterminal and reference angles to find the trigonometric ratios for all angles. We solve some examples in how to find the trigonometric rations aof any angle with the use of reference triangle ang angle. Happy learning and enjoy watching! #math #tagalog #trigonometry
