If 2sinx-cos2x=1 then prove that sinx^4-sinx^2=2-root5
Hello candidate,
There is a limitation on the number of answering modes available on this platform, its not possible from my part to provide you with the detailed solution.
However, you have to first open up the cos 2x term into sin square x function and solve it keeping one expression as your base expression and then solving the second expression in order to get your desired result.
Feel free to ask other queries!!
