Prove this trigonometric equation;<br><br> - tan^2x + sec^2x = 1,
alekssr [168]
Hey there :)

- tan²x + sec²x = 1    or    1 + tan²x = sec²x

sin²x + cos²x = 1 
Divide the whole by cos²x

\frac{sin^2x}{cos^2x} + \frac{cos^2x}{cos^2x} = \frac{1}{cos^2x}

\frac{sinx}{cosx} = tanx so \frac{sin^2x}{cos^2x} = tan^2x
and
\frac{1}{cosx} = secx so \frac{1}{cos^2x} = sec^2x

Therefore,
tan²x + 1 = sec²x
Take tan²x to the other side {You will have the same answer}

1 = - tan²x = sec²x or sec²x - tanx = 1

What is the factor of the problem? <br> ~plz help I cannot get this wrong !
IRINA_888 [86]

Answer:

(x-3)(x+2)

Step-by-step explanation:

So, if we start with x^2+-x-6, we need a set of numbers that equal -x when added, and -6 when multiplied. So, -3 and 2 work, so we take them and plug them into this (x-3)(x+2)

hope this helps. i can explain more if you need it.
