Integral of sin2x/1+sin^2x​

Answer»

\implies  \displaystyle\int \:\sf \dfrac{sin \: 2x}{ {sin}^{2}x }dx

We know that :-

\sf sin \: 2t \:  = 2 \: sin \: t \: cos\:t

\implies  \displaystyle\int \sf\dfrac{2sin \: x \: cos \: x}{ {sin}^{2}x } dx

\implies 2 \displaystyle\int \:\sf \dfrac{ \: cos \: x}{ {sin} \: x } dx

\sf \: Let \: sin \: x \:  = m \\  \sf   \therefore \: cos \: x \: dx = dm

\implies  2\displaystyle\int \:\sf \dfrac{ dm}{ m}

\implies 2  \sf \: log (m) + <klux>C</klux>

Where c is constant.

Put m = sin x

\implies   \sf \:2 log (sin \: x) + c

∫ 1 dx = x + C

∫ sin x dx = – cos x + C

∫ cos x dx = sin x + C

∫ sec²x dx = tan x + C

∫ csc²x dx = -cot x + C

∫ SEC x (tan x) dx = sec x + C

∫ csc x ( cot x) dx = – csc x + C

∫ (1/x) dx = ln |x| + C

∫ EX dx = ex+ C

Answer these below and whoever answers this below step by step first will be marked brainliest ​

Answer»

ANSWER:

a) 1/3 : 1/4 : 1/5

= (1/3) ÷ (1/4) ÷ (1/5)

= (1/3 × 4/1) ÷ 1/5

= 4/3 × 5/1

= 20/3

b) (11/7 ÷ 33/14) × 2/5

= (11/7 × 14/33) × 2/5

= 2/3 × 2/5

= 4/15

c) -1/3 + -4/9 + -5/12 + 1

= The L.C.M. of the denominators are 36

= The fractions will be -

= (-12/36) + (-16/36) + (-15/36) + (36/36)

= [(-12) + (-16) + (-15) + 36] ÷ 36

= -7/36

d) 17/18 - (-8/9)

= The L.C.M. of the denominators are 18

= The fractions will be -

= (17/18) - (-16/18)

= [17 - (-16)] ÷ 18

= 33/18

Answer»

Step-by-step EXPLANATION:

please mark me brainliest and follow

profit of Rs.10 PER BAG of basmati RICE

loss of Rs.5 per bag of non-basmati rice

i) 3,000 bags of basmati rice ×10=30,000 profit

5,000 bags of non-basmati rice ×5=25,000 loss

30,000−25,000=5,000 net profit

ii) Let x be the number of bags of basmati rice

10x=6,400×5

10x=32,000

x=

Ravi said that, every pair of supplementary angles is a linear pair. Do you aghim? Why?​

Answer»

Answer:

Yes, EVERY pair of SUPPLEMENTARY ANGLES is a linear pair.

This is because, supplementary angles mean that the sum of the angles is 180° and we KNOW that angle 180° is a straight line.

Therefore, a linear pair is that which contains two angles who add up to form 180° or straight line.

Hence every pair of supplementary angles is a linear pair.

Please solve question no. 19,21(i),(ii) and (iii) ASAPBut if you don't know it's answer then don't answer this question so that someone who know it's answer can answer it​

Answer»

Answer:

21(ii) Tn = sin^n x+ cos ^nx

T4= sin^4x + cos^4x

T6 = sin^6x + cos^6x

2T_6 -3T_4+10

= 2(sin^6x+cos ^6)-3(sin^4x+ cos ^4x)+10

= 2{(sin^2x)^3+(cos ^2x)^3}- 3{(sin^2x)^2+(cos^2x)^2}+10

[a^3+b^3=(a+b)(a^2-ab+b^2)

a^2+b^2 = (a+b)^2-2ab & sin^2 THETA + cos^2 theta= 1]

USING these

= 2[(sin^2x+cos^2x)(sin^4x+cos^4x-sin^2x cos^2x)3sin^4x- 3cos^4x+10

= 2sin^4x+2cos^4x-2sin^2x cos^2x - 3sin^4x - 3cos^4x+10

= - sin^4x - cos^4x -2sin^2x cos^2x+10

= 10-[(sin^2x)^2+(cos^2x)^2+2sin^2x cos ^2x]

=10-(sin^2x+cos^2x)^2

=10 - 1 =9
