how to calculate cosecant

- 1 x For x R - (-1,1), if q is an angle whose cosecant is x, then we say that cosecant inverse of x is q and write cosec -1 x = q . In particular, if q [ -p/ 2, p /2] - {0}, then q is called the principal value of cosec -1 x. For ..

Let, The mass of the organic compound taken be = W g Increase in the mass of magnesium perchlorate tube = W 1 g Increase in the mass of the KOH tube = W 2 g So, Mass of water formed = W 1 g Mass of carbon dioxide formed = W 2 g ..

Let, The mass of the organic compound be = W g Mass of the precipitate of BaSO 4 = W 1 g From stoichiometry, BaSO 4 = S 1 mol 1 mol 1 molecular mass 1 atomic mass 233 g 32 g Therefore, ..

Let, The mass of silver salt taken for ignition be = W g Mass of silver left behind after ignition = W 1 g We have RCOOAg = Ag1 equivalent 1 equivalent The equivalent mass of silver is 108. Hence, the mass of silver salt that would leave 108 g of residue (equivalent mass of the silver) i..

Let, The mass of the organic compound taken be = W g Volume of air displaced = V 1 mL Atmospheric pressure = P mm of Hg Room temperature, T 1 = t o C = (t + 273)K Aqueous tension at t o C = p mm of Hg Pressure of the dry air, P 1 = (P-p) mm Hg ..

Let, The mass of the organic compound taken be = W g Volume of nitrogen collected = V 1 g Atmospheric pressure = P mm Hg Temperature at which gas is collected = T 1 K Therefore, Pressure of the N 2 gas, P 1 = (P - p) mm of Hg ..

Calculate empirical formula Use vapour density if given If molecular weight given, calculate 'n' using this formula Molecular formula = n x empirical formul..

Knowing the solubility product of a sparingly soluble salt like AgCl, PbI 2 , BaSO 4 etc. the solubility of the salt can be calculated..

Calculate the percentage by weight of each element. Find out relative number of atoms by dividing percentage of weight by atomic weight. Choose the simplest ratio and the smallest, divide all the ratios by it. If whole numbers are not obtained, then multiply it by a smallest in..

Consider an ideal gas enclosed in a cubical vessel of edge L. Take a corner of the vessel as the origin O and the X-,Y-, Z- axes along the edges (figure 1). Let A1 and A2 be the parallel faces, perpendicular to the X-axi..
