on wat?

this is the link where u quoted me https://www.nairaland.com/post/40582247 my number is in I want u to modify it and clear the number off thanks

Homeboiy:
yes your right, thanks for the correction
but it came out in our exam last week n I solved and got 6
Thank you

Yes boss.

Example II solution is wrong. Before you use L'Hospital's rule, you must have used direct substitution and be sure you got an indeterminate/undefined expression like 0/0, infinity/infinity and to mention a few. Example II using direct substitution will have given you the answer you looking for. The answer is zero and not 2... You can modify example II if you want to use L'Hospital's rule. Just replace x with x-2 in the denominator and your solution will be true...

**cheers**

Actually, I wasn't so much abt the question, just to tell him the "how". It was a non verified question, don't mind me


Even... limx---2 (x^2 -4/2) = limx-- 2 [(x-2)(x+2)/x ]= 0/2 = 0

Even the best of us make mistakes. Thanks bro!

Just pointing it out cos the post will be here forever and someone will be like...

And I'm saying you've done well, man

A simple question for gurus. Find the nth term the sequence : 4, 13, 26, 43...

pls help, in a leap year, a baker baked 500000 loaves of bread, how many loaves did he bake in February, if his working day are Monday to Saturday

is d question corect??..pls solve it

please I need harder question in maths like permutation calculus binomial distribution

yusman14:
is d question corect??..pls solve it

Very correct....

Tpappie:
Very correct....

Tn=2n^2+3n-1

lordbeans:
Tn=2n^2+3n-1

Correct

Please maths Gurus, can anyone help me with the solutions to this questions.

Q.1

Q.2

Q.2

Thanks so much. I really appreciate

please i need a recomended best mathematics past questions and answers text books for checkpoint exams, american exam and cowbell competition for junior secondary schools.

Please, I need a solution to this question asap.

Given that
xCosA + ySinA = 8, xCosA - ySinA= 6. Show that x squared + y squared = 100. I have solved but not reached any headway... Thanks a lot...

wrong question.

lordbeans:
wrong question.

Please can you explain why it is wrong?

Squaring both sides of the equation gives

x²cos ²A + y²sin²A + 2xycosAsinA =64......(1)
x²cos ²A + y²sin²A - 2xycosAsinA =36......(2)

Add (1)+(2), gives 2x²cos ²A+2y²sin²A=100......(3),

hence the only way x²+y²=100, is if cos ²A=1/2 and sin²A= 1/2; which only occurs when A=pi/4.

so I think I should have said that the question is only true when A=pi/4.

That was exactly my problem. Someone gave me to solve and I just got stuck there. I even tried using compound angle formula, it didn't work. I tried solving simultaneously, I got xCosA as 7 and ySinA as 1. Thanks a lot though

U re welcome.

Good day house, please help me out with soft copies of any good materials on mathematics and further maths. God bless you.

please can someone help me out on this question: a/b is a fraction. If 2 is added to the numerator, the value of the fraction is 1/2. If 3 is added to the denominator, the fraction has a value of 1/3. the value of the sum of a+b is:
