A memory trick that I learned for trigonometric values is:

Sin: opp/hyp

Cos: adj/hyp

tan: opp/adj

A building is 60ft high From a distance at A on the ground the angle of elevation to the top of the building is 40 From a lil nearer at B the angle of elevation is 70 Find the distance from A to B?

Using the formula: tangent = opposite/adjacent whereas tangent angle = height/ground distance, will help to solve the problem


What does ine cosine and tangent mean?

Sine, Cosine and Tangent (abbreviated to sin, cos and tan) are three trigonometric ratios. They are used to find angles and sides in right angled triangles. There are more, but I will only explain these three.In a right angled triangle, the hypotenuse (abbreviated to hyp) is ALWAYS opposite the right angle and is the longest side. The opposite (abbreviated to opp) is the side opposite to angle 'theta' (Θ, the unknown angle when finding angles). The adjacent (abbreviated to adj) is the side adjacent to (connecting) angle Θ and the right angle.Here are the formulae:sin = opp/hypcos = adj/hyptan = opp/adjThe made up word 'SOH CAH TOA' can help. It is made from the first letters of 'Sine is Opposite over Hhypotenuse. and so on'.You may also have heard of Inverse sin, cos and tan (written as sin-1, cos-1 and tan-1). You use these to find an angle. For example: if you are finding the sine of angle Θ, and the opposite is 40 and the hypotenuse is 68, 40/68 = 0.588235..., then, sin-1(0.588235...), so, Θ = 36.0 (to 3 significant figures).If you have a scientific calculator, you can use the sin, cos and tan buttons to help work out sides and angles. Usually, pressing 2ndF or SHIFT then sin, cos or tan gives sin-1, cos-1 or tan-1.To find sides of a right angled triangle using sin, cos or tan, you need an angle other than the right angle. Let's say you have a triangle in which opp is 40 cm and you want to find hyp. the angle is 45°. This is the process:You have opp and you need to find hyp. Therefore we use sin = opp/hyp.sin 40° = 40/hyp40 * sin 40° = hyphyp = 25.7 (to 3 sig. fig.)I hope I've kept this clear and I hope you now understand sine cosine and tangent well.

How do you do sine and cosine?

It would help if I knew a little more information about what you're looking for, in order to better answer your question, but here are the basics.For a right triangle, given one of the angles that is not the 90° angle:sine is the ratio of the length of the side opposite the angle divided by the length of the hypotenuse.cosine is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse.One way to remember this is: Sine, Cosine, Tangent; then think of Old Harry Always Has Old Apples. Sine = O/H, Cosine = A/H, and Tangent = O/A,where O is the Opposite side, A is the Adjacent side, and H = Hypotenuse.Another one that somebody taught me is: Oh Heck Another Hour Of Algebra. Pick whatever helps you to remember.


Where to use sine and cosine in physics?

Sine and cosine functions are used in physics to describe periodic phenomena, such as simple harmonic motion, sound waves, and alternating currents in circuits. They help in modeling phenomena that exhibit oscillatory behavior over time or space. Sine and cosine functions are also used in vector analysis to analyze the components of vectors in different directions.


How do you find sin?

sin is everywhere. The Bible will teach you what it is, and you will see it all over the place. Now if you are looking for mathematical instructions for a trigonometry class about finding a sine, cosine, and tangent... I can't help you. Find a math tutor.


How do you find the sin of a triangle?

Sin is opposite over hypotenuse. Just think of this to help you: SOH-CAH-TOA Sine = opposite over hypotenuse Cosine = adjacent over hypotenuse Tangent = opposite over adjacent Hope that helps you.

What is the square-root of a tangent?

The tangent is essentially the derivative of the function. The square-root is just what ever function that is takes two of that function to equal the tangent. If you need further help on this question just send me a message on my message board and id be glad to help you out.
