Istan Rabovsky was born in 1930, in Hungary.

Istan Rabovsky's birth name is Istvan Rabovsky.

Actually, there is no single country in the Middle East that has istan in its name. Most of the Central Asian countries end with istan such as Kazakhstan and Turkmenistan. ^ That's what the question was asking. TurkmenISTAN, AfghanISTAN, UzbekISTAN, PakISTAN. --- Its a Turkish word that bounds them meaning 'where x people live'. Kürd-istan, Türkmen-istan etc.

AfghanistanPakistanTurkmenistanUzbekistanThe suffix is actually -stan, not -istan. This suffix is Persian for 'Land of'. Two other countries contain the suffix -stan and they are Kazakhstan and Kyrgyzstan.

tan2(theta) + 5*tan(theta) = 0 => tan(theta)*[tan(theta) + 5] = 0=> tan(theta) = 0 or tan(theta) = -5If tan(theta) = 0 then tan(theta) + cot(theta) is not defined.If tan(theta) = -5 then tan(theta) + cot(theta) = -5 - 1/5 = -5.2

cos2(theta) = 1 cos2(theta) + sin2(theta) = 1 so sin2(theta) = 0 cos(2*theta) = cos2(theta) - sin2(theta) = 1 - 0 = 1

The only real solution is theta = 0For theta < 0 square root of 3 theta is not defined.For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative.The only real solution is theta = 0For theta < 0 square root of 3 theta is not defined.For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative.The only real solution is theta = 0For theta < 0 square root of 3 theta is not defined.For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative.The only real solution is theta = 0For theta < 0 square root of 3 theta is not defined.For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative.

It is cotangent(theta).

Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.

cos2(theta) = 1 so cos(theta) = Â±1 cos(theta) = -1 => theta = pi cos(theta) = 1 => theta = 0

There are three of them. Granted this means that there are different variations of all three. I'll show you the variations as well. This is coming straight from my Math 1060 (Trigonometry) notebook. Sorry there is no key to represent the angle; Theta.1. Sin2 (of Theta) + Cos2 (of Theta)= 1Variations: Sin2 (of Theta) = 1- Cos2 (of Theta)AND: Cos2 (of Theta) = 1-Sin2 (of Theta)2. Tan2 (of Theta) + 1 = sec2 (of Theta)Variations: Tan2 (of Theta) = Sec2 (of Theta) -13. 1 + Cot2 (of Theta) = Csc2 (of Theta)Variations: Cot2 (of Theta) = Csc2 (of Theta) -1

tan (theta x theta) : must square the value of the angle, theta, before applying the trig function, tangent.
