  • kalau pangkat 3 kk ga tau , tpi kalo pngkat 2 ketemu caranya
    [tex] \frac{ sin^{2}x + cos^{2} x }{cos x} = sec x[/tex]
             [tex] \frac{1 }{cos x} = sec x[/tex]
                 sec x = sec x

    atau
    [tex] \frac{ sin^{2}x + cos^{2} x }{cos x} = sec x[/tex]
    [tex] \frac{ sin^{2}x + cos^{2} x }{cos x} = \frac{1 }{cos x}[/tex]
    [tex] \frac{ sin^{2}x + cos^{2} x }{cos x} = \frac{ sin^{2}x + cos^{2} x  }{cos x}[/tex]

    hehehe, maaf kalo salah :D
