Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side

Hi there!
83,960.11 rounded to the nearest hundred would be 84,000. The 960 rounds up to 1,000+, so that is your answer.
You can't round down on this, since 6 is bigger than five it tells 9 to go up and cancel out to be a zero.
Hope this helps!
