Prove the trig identity: (tanx/1+secx)+(1+secx/tanx)=2cscx
lakkis [162]
=[(sinx/cosx)/(1+1/cosx)] + [(1+1/cosx)/(sinx/cosx)]

=[(sinx/cosx)/(cosx+1/cosx)]+[(cosx+1/cosx)/(sinx/cosx)]

= [sinx/(cosx+1)] + [(cosx+1)/sinx]

= [sin^2x+(cosx+1)^2] / [sinx (cosx+1)]

= [2+2cosx] / [sinx(cosx+1)]

=[2(cosx+1)] / [sinx (cosx+1)]

= 2/sinx

= 2 cscx

(I think this will be helpful for you. if you can see the picture, it has more detail in it.)

Through point (0, 10) and PERPENDICULAR to the line through (-2, -9) and (-4, -17)?
inn [45]

Compute the slope of the line through (-2, -9) and (-4, -17):

\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4

Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes

y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}
