Question

Differentiate tanx(where x in degrees)

Answer 1

\[\tan x ^{o}\]

Answer 2

that is degree

Answer 3

sinx/cosx, cos^2x+sin^2x/cos^2x, 1/cos^2x, sec^2x

Answer 4

x is in degrees

Answer 5

yes. it can also be theta

Answer 6

no

Answer 7

\[\frac{d(\tan \pi \frac{x}{180})}{d \pi \frac{x}{180} } \times d \frac{\pi \frac{x}{180}}{dx} = \sec^{2} \frac{\pi x}{180} \times \frac{\pi}{180} \]

Answer 8

perhaps something like this,not sure

Answer 9

thats what is written in sol

Answer 10

they have just change degree into radians thats all

Answer 11

No,
\[\frac{d}{dx}tanx=\sec^2{x} \] is only possible when x is in radians.

Answer 12

reqd ans is (pi)/180 (sec^2x) (here also x in degrees)
actually before differentiating u have to convert x degree to radians )
and 1 degree = (pi)/180 radians

Answer 13

yes that's what i said.

Answer 14

okay..thanks!
