thankyouJesus:
For now, I base in Nairaland.

why r we nt having maths tutorial again na

pls tankujesus, can u solve dis
1.dy/dx= 1-x^2/x dx
2. If d diff. Btw d length n wide z 6cm, given d area to be 135cm. Find d length.
3. Find d n sides of d regular polygon, given each sides to be 144 degree.

thankyouJesus:
[b]Ekaro nibi ba yin o.
No time to waste.

Example 1: No 32, 1978
if sec²¤ + tan²¤ = 3, then the angle ¤ is equal to.
Solution:
sec²¤ + tan²¤ = 3
recall that
tan²¤ + 1 = sec²¤
substituting, we have
1 + tan²¤ + tan²¤ = 3
1 + 2tan²¤ = 3
2tan²¤ = 3 - 1
2tan²¤ = 2
dividing both sides by 2
tan²¤ = 1
square root both sides
tan¤ = 1
¤ = tan^-11
¤ = 45

Example 2: No 34, 1985
without using tables, calculate the value of 1 + sec²30.
Solution:
1 + sec²30
recall that sec¤ = 1/cos¤
re-writing the equation
1 + 1/cos²30
using special angle, cos30 is root3/2
1 + 1/[root3/2]²
1 + 1/3/4
1 + 4/3
7/3

Example 3: No 8, 1983
given that cosz = l, where z is an acute angle, find an expression fos [cosz - cosecz]/(secz + tanz).
Solution:
[cosz - cosecz]/(secz + tanz)
recall that:
1. Cosecz = 1/sinz
2. Secz = 1/cosz
3. Tanz = sinz/cosz
4. Sin²z + cos²z = 1

Very good.

Example 4: No 42, 1989
4sin²x - 3 = 0, find x if 0 < x < 90.
Solution:
4sin²x - 3 = 0
4sin²x = 3
sin²x = 3/4
sinx = root(3/4)
x = 60.

I am being lazy to type question this morning.

Any question or do you have a question for "us" to solve together?

Bye bye to trigonometry concerning JAMB, our next topic will be a simple one.

How did you get their questions

dceabec

thankyouJesus:
my bad, I made a mistake when differentiating,
dy/dx = x^2 - 2x - 2.
Note: The method is right, but the dy/dx is wrong

y= x^3/3-x^2-2x+5, then, u jst wrote x^2-2x-2. Hw did u differentiate dat.

thankyouJesus:
Cc dupre

i dnt undastand hw u get d ans wen u put ............ X2-x-2

thankyouJesus:
Good morning all, something hit me, nobody, I repeat nobody has ever ask a question from either differentiation and integration classes. I can't evaluate, re-strategise, e.t.c when there is no feeback (questions).
I want to slow down because of questions, am waiting.

+

pls can u shed more light on differentiation maximum n minimum value

thankyoujesus, i really appreciate ur contributn on dis forum. May God blez u.
