It sounds weird but I don’t know how to use these☺️. A quick tutorial would be appreciated
Already a topic on this, don’t have link sorry. give it a search
Quick summary: ratios of triangle
Sin and cos are side over hypotenuse, tan is side over other side.
Cos (side a) = b/c
Tan (a) = a/b
Ok. There are already topics like this,but I’ll help.
Sine can only be done with right angles.
A right angle has a hypotenuse(the longest edge),Opposite(the edge opposite to the hypotenuse),Adjacent(adjacent to the hypotenuse) edge.
To calculate sine,we first find out the length of Hyp and Opp. Then we divide the Opp by Hyp. The answer is called Sine theta.
**Sorry that I didn’t use a topic **
Thx for that
Both of You
Cosine is adjacent divided by hypotenuse and tangent is opposite divided by adjacent. There is also something called a reverse tangent, which adjacent divided by opposite.
Sine,Cosine and Tangent are called trigonomometric ratios.
Thanks. I don’t need this topic anymore but I won’t close it in case someone else needs help or I’ve forgotten something and need to refer back to it.
