There are a lot of things they don't teach you in school, and one of them is how to use an escort service. Somehow society seems to think that men should just know how to do this. Why they make this assumption is beyond me. The truth is that most guys don't have a clue about ...
Use cosine tables to find the angle the ladder makes with the ground. Calculate the ratio of the adjacent side to the hypotenuse, and then look up the ratio in a table of cosines to find the corresponding angle. Calculate the angle the ladder makes with the wall by subtracting the angle ...

We can use the following diagram: The sine of the angle will be the quotient between the opposite side and the hypotenuse, in this case it... Learn more about this topic: Trigonometric Ratios | Definition, Similar Triangles & Examples ...
So we need to find the Sine of the Angle.Use the formula:=SIN(A2/C2)Press EnterAs you can see the Sine of the angle of the triangle.The above method was for having sides of the triangle. If you have the angle in degrees and you need to find the Sine of that angle.Use the ...
Sine, cosine and tangent, often shortened to sin, cos, and tan in mathematical operations and on calculator keys, are the most basic trigonometric functions. All three are based on the properties of a triangle with a 90-degree angle, also known as a righ
Hint: In this question, we have been given a condition of two vectors and we need to find the\[sine\] of the angle between them. According to the standard formula, the angle $\theta $ between two vectors \[\overrightarrow u \] and \[\overrightarrow v \;\] i...
ASIN sin(θ) = opposite/hypotenuse ACOS cos(θ) = adjacent/hypotenuse ATAN tan(θ) = opposite/adjacent ACOT tan(θ) = opposite/adjacent The trigonometric functions relate an angle expressed in radians or degrees to two out of three sides in a right triangle. What is the angle θ? The Gr...
In trigonometry, frequency refers to how many cycles a function finishes during a specific interval. Learn how to find the frequency of a trig function, including sine, cosine, tangent, and other trigonometric functions. Frequency of Trig Functions Frequency is a measure of how often something ...
To calculate the height of the slide we can use the sine: sin(36) = y/4 And therefore y = 4*sin(36) = 2.35 meters. Now we can check whether tan(36) is indeed equal to 2.35/3.24. We find tan(36) = 0.73, and also 2.35/3.24 = 0.73. So indeed we did everything correctly. ...
