Trigonometric Functions Examples Videos Worksheets Solutions Scroll down the page for more examples and solutions on the trig identities. reciprocal trigonometric functions there are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. the reciprocal cosine function is secant: secθ = 1 cosθ. the reciprocal sine function is cosecant, cscθ = 1 sinθ. The following diagram shows how to use sohcahtoa. scroll down the page for examples and solutions. trigonometric functions: sine of an angle. we first consider the sine function. the sine of an angle is the ratio of the opposite side to the hypotenuse side. sine is usually abbreviated as sin. sine θ can be written as sin θ.
Trigonometric Equations Formula With Worksheets Examples, videos, worksheets, solutions, and activities to help students learn the trigonometric functions: sine, cosine, tangent. basic trigonometry. The trigonometric functions have values of θ, (90° θ) in the first quadrant. the cofunction identities provide the interrelationship between the different complementary trigonometric functions for the angle (90° θ). sin (90°−θ) = cos θ. cos (90°−θ) = sin θ. tan (90°−θ) = cot θ. cot (90°−θ) = tan θ. Law of sines and cosines worksheet. (this sheet is a summative worksheet that focuses on deciding when to use the law of sines or cosines as well as on using both formulas to solve for a single triangle's side or angle) law of sines. ambiguous case of the law of sines. law of cosines. sine, cosine, tangent worksheets. sohcahtoa. Sin, cos and tan are trigonometric functions. the angle can be called anything but it is often referred to as ϴ (theta). sin(θ)sin(θ) when we input a given angle into sin(θ)sin(θ) it gives us the ratio between the opposite length and the hypotenuse. it tells us how many times bigger the opposite is than the hypotenuse.
