So question I put in my calculator Sin(15) and it gives me like a really weird answers instead of a number?
@sciencemadesimple8924Ай бұрын
Try pressing the S D button, which will transform your answers between numbers and surds. It is also worth checking your calculator is in degrees (there's a little D at the top) and not radians (a little R at the top).
@typ07615 ай бұрын
For the middle triangle, I don't get it, cos=15/a, a we don't know the value of, so, for the final answer, you need to devide 15/cos, but we don't know cos. Please help
@sciencemadesimple89245 ай бұрын
Because the angle is 55, you divide 15 by "cos15" - using the calculator function for cos, as I demonstrate at 6:39
@teyannabenjamin383223 күн бұрын
When do we use inverse? Is it just for TAN?
@sciencemadesimple892422 күн бұрын
No, each of sin, cos and tan have their own inverses (usually the second function above the main sin, cos, tan button). You use the inverse when you have two sides and are trying to find an angle.

@sciencemadesimple89243 ай бұрын
Because you only need one angle, one side, and to find the length of the lettered side (in this case, a). If you wanted to find the opposite, you could use Pythagoras' theorem after finding a.

Then you use a slightly different method using the Cosine rule. I don't have a video on it, unfortunately, but there's a guide here: www.mathsisfun.com/algebra/trig-solving-sss-triangles.html
@euelakliluthejoker7506Ай бұрын
ayo i understand whats going on but this is completely different from what i am learning . For the 3rd question shouldn't you press inverse tan then divide 5 over 8 ? For the rest of the new viewers , yall can scroll down to see the other comments that were helped.
@sciencemadesimple8924Ай бұрын
So you could do tan^-1 (5/8) straight away. That's doing more or less the same thing I am, but just does it in fewer steps. The explanation above just breaks it down a little more.
