【図形と計量(三角比)】

Enlightenment, less does not ask for the value of the trigonometric fraction of the next angle. First, the past 190 degrees. Now what happens to the sine cosine tangent? Well, what happens to the tangent I said here on the previous page, but first of all, as usual, the semicircle I will continue to wear it Now. I imagine a radius with a 90 stage inclination between the positive counseling of the x axis, but 90 stages. Is this isn’t it So this time op radius, op! You should come here like this, but here Well. I know if this is okay. 90 positions, so I wasn’t conscious of 30 stages, 60 stages or 45 degrees, Since this is also other than that. It is good to imagine the radius for the time being. 1. 1. Well here in coordinates, 1 at r Know and alteration. The coordinates of p Some people erroneously write this as 10, but since the x coordinate is zero and the by coordinate is 1, it will be 01. Yes, after that, if you know the positions of 01 and r of this p, it will be this one Y Haar for Earl is 1. Wai is a stone, so this is 1 cos 90 units. It was a right angle. X, r is 1 x is zero. So 90 measures for cos It are likely to be 0, so this is ok. I formerly paid attention to it. As for the turn position and 90 stages I had well, is the definition of tangent x minutes of cherish. When I think about doing it. Kusu is a zero day. It’s crazy, but 2 doesn’t allow this life to come to the denominator 0. Well, I don’t allow it to be divided among 0, So this, regrettably don’t think this wasn’t characterized Not characterized. Not characterized Now 90 positions “re no longer” there. No and zero are different. Zero is a numerical value of zero, but none is a tangent 90 magnitude cost. It means that it doesn’t exist anymore. There is a sign 90 stages. 1 cos. 90 stages is also zero. This is because the denominator is not 0 and the numerator is zero. It’s, ok, so the turn direction and 90 measures. It can be an undefined narration, though. This is not good because the denominator is 0 isn’t it Line 90 degrees 1 cos 90 degrees. 0. Tangent 90 was not defined . .
