Hallow Stary Funs; I have one math problem hope I can getsolution here;
The question is:

Integrate (sec2x(cot x) 1/2) dx;

I need your solution in details please I’ll be very much
grateful.

Integrate (sec2x(cot x) 1/2) dx;

Solution

Remember that, cot x = cos x/sin x

Then (cot x) ½ = (cos x/sin x)1/2 and
can be written as;

(sin x/cos x)-1/2 ; so we substitute it with (cot
x) 1/2

= Integral of (sec2x (sin x/cos x)-1/2 )
dx

= Integral of (sec2x (tan x)-1/2) dx

= Integral of [sec2x (1/ (tan x) 1/2)]
dx

Now let u = tan x

du­­/dx = sec2x;
 then dx = du/sec2x

Now from Integral of [sec2x (1/ (tan x) 1/2)
 ] dx

= Integral of [sec2x (1/ (u) 1/2)]x du/sec2x;

= Integral of 1/ u ½ du = u- ½ du;

= 2u½ ; but u = tan x

Therefore = 2(tan x) ½ + c

Hope this is the best solution for you.

Badshah, mbona sielewi mpangilio wa hiyo math? kwani najua kuna powers humo but zinachanganya na namba za kawaida, the question is good also to me can you specify where powers are? sorry for any inconvinience.

Yes I can

Hassan, tatizo powers haziandikiki humu katika Forum lakini nimejaribu kuziweka katika Microsoft word then nika capture kama image yake ili zionekane vizuri:

I hope this is very good, napenda sana kujua Mathematics but ni kazi sana kumtafuta mwalimu atakayekufundisha kwa dhati na kwa kina mpaka uelewe, but mi naona pia ingesaidia kama kungewekwa humu forum maalumu kwaajili ya somo hili tu ili wafaidike wengi sana, au wenzangu mnaonaje?

zulfa, umeongea point but inategemea na wadau wa hili somo kwasababu forum inabidi iwe na wadau na wenye maoni wengi sasa utakuta wanaotaka ni wanne tu kati ya 100, ila kama utahitaji kujifunza walimu c wapo wengi tu unalipia tuition wanakuteach.

Yes I can

ndiyo Hassan, hata mimi hilo naelewa lakin unajua nn, ili ufaulu discussion n muhm sana, hwez kufaulu kw kusoma kitabu tu, inabidi upate mawazo ya watu tofauti na idea mbalimbal. kwa mfano nasoma tuition and nikipata question nikiuliza watu tofauti na kupata majibu mbalimbali hiyo ni good challenge.

zulfa, mdogo wangu kweli jitahidi. mm nilipuuzia sana ila nilipofika chuo nikasomea masomo ya Business yaan nilikuwa katika wakati mgumu kwani nilikuwa cjui math hata kidogo ikabidi nitafute tuition ya ziada.
