Please sølve this question of MATHS.......✌​

Answer»

ANSWER:

F(X) = secx

Step-by-step explanation:

\int\limits {e^x(tanx+1)secx}\,dx

= \int\limits {e^x(tanxsecx+secx)}\,dx

= \int\limits {(e^xtanxsecx+e^x secx)}\,dx ............................(i)

LET,

e^xsecx = y

(e^xsecx + e^x secx \times tanx )dx= dy

Now, (i) ............

= \int\limits dy

= y + c

= e^xsecx + c = e^x f(x) +c

So, f(x) = secx

When , Theta = 120 then , what will be the area of triangle ?​

Answer»

1/2×sides which form the angle ×sin theta

Now in case the sides which form the angle is equal can be represent as 1/2×a×a×sintheta (here a denotes side length)

1/2×a^2×sintheta

In case of angle forming sides are unequal can be represent as

1/2×ab×sin theta (here a and b are side length which forms the angle)

Now u will thinking that from where this formula come it is same as 1/2 × base ×HEIGHT

Now u will thinking the formula i discussed above have no height how it can be possible

Now let me explain u , u saw in formula asintheta or b sintheta is ur height and other side is ur base now from where it CAME .IT came from TRIGONOMETRY.

Solve y = p tan p + log (cos p), where, =

Answer»

Given

y=p\TAN p+\log (\COS p)

Differentiating the above w.r.t. x

\FRAC{dy}{dx}=p\sec^p\frac{dp}{dx}+\tan p\frac{dp}{dx}+\frac{1}{\cos p}\times(-\SIN p)\frac{dp}{dx}

\implies p=p\sec^p\frac{dp}{dx}+\tan p\frac{dp}{dx}-\tan p\frac{dp}{dx}

\implies p=p\sec^2p\frac{dp}{dx}

\implies \sec^2p dp=dx

\implies\int \sec^2p dp=\int dx

\implies \tan p=x+c where c is a constant

\implies x=\tan p-c

Thus,

y=p\tan p+\log (\cos p) and x=\tan p-c is parametric solution of the equation, where p is a parameter...................
