Simplify sec (2x) sec(2x) sec ( 2 x) Nothing further can be done with this topic. Divide by . From above, we found that the first derivative of sec^2x = 2sec 2 (x)tan(x). $\sec^2{x} \,=\, 1+\tan^2{x}$ $\sec^2{A} \,=\, 1+\tan^2{A}$ Therefore, you can write the square of secant function formula in terms of any angle in this way in mathematics. Step 3. Sec 2 A = 1 + tan 2 A. Let theta be a symbol, which represents an angle of a right triangle. d dx (sec2(x)) = 2sec(x) ⋅ sec(x)tan(x) = 2sec2(x)tan(x) Answer link. x= \pi + 2k\pi x = \pi/3 + 2k\pi x= -pi\/3 + 2k\pi Since sec (x)=1/cos (x), the expression becomes 1/cos^2 (x) - 1/cos (x) = 2 Assuming cos (x)\ne 0, we can multiply everything by cos^2 (x): 1-cos (x) = 2cos^2 (x). Take the inverse secant of both sides of the equation to extract x x from inside the secant.rewsnA 1 redisnoc uoy fi ylraelc pihsnoitaler moerehT-naerogahtyP eht ees nac uoY . Use the form asec(bx−c)+ d a sec ( b x - c) + d to find the variables used to find the amplitude, period, phase shift, and Convert the solutions: cos(x) = −1 ⇔ x = π+ 2kπ. In fact, most Linear equation. #color(red)(bar(ul(|color(white)(a/a)color(black)(sin^2x+cos^2x=1)color(white)(a/a)|)))# divide all terms on both Simplify (sec(x)^2)/(tan(x)) Step 1. For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music… In Trigonometry, different types of problems can be solved using trigonometry formulas. Simplify (sec^2 - 1)/sec^2 Ans: sin^2 x Replace sec^2 = 1/ (cos^2 x into the expression , we get: (1/ (cos^2 x - 1))/ (1/ (cos^2 x)) = ( (1 - cos^2 x)/cos^2 x) ( (cos^2 x)/1) = Since (1 - cos^2 x) = sin^2x, therefore: (sec^2 x - 1)/sec^2 x = sin^2 x. If you are using a scientific calculator, then you could push the buttons in the following order: inputnumber for x x, cos, x2, x−1 cos, x 2, x − 1. Use the Chain rule.
