Sep 15, 2019 ... A nice trick to use here is a conjugate-type of thing. Multiply top and bottom by 1-tanx, then factor out a cotx from the top after expanding, ... Plot the cotangent function over the domain - π < x < 0 and 0 < x < π . x1 = -pi+0.01:0.01:-0.01; x2 = 0.01:0.01:pi-0.01; plot(x1,cot ... Nov 15, 2018 ... COMEDK 2015: The number of solutions of the equation |cot x|=cot x+(1/sin x), (0 le x le 2π) is (A) 0 (B) 1 (C) 2 (D) 3. The period of the cot(x) cot ( x ) function is π π so values will repeat every π π radians in both directions. x= ... Jul 2, 2017 ... The following question is asked under a section on Trig Identities Simply states Simplify cosec x + cot x We managed to get this far: 1 sin ⁡ x + cos ⁡ sin ⁡ x. ... x where f(x) is negative in interval notation. Write the set of all x where ... (1); ( f+g )(1); ( f-g )(4); ( {g}/{f} )(-1); ( f○ g )(1); ( g ○ g )(-5 ... Press [x-1] [ENTER] to complete the calculation.
