tan theta +cot thetha =2, Squaring both sides, (tan theta+cot theta)²=(2)², tan²theta + cot²theta +tantheta.cot theta=4 tan²theta + cot²theta +1=4, tan²theta + cot²theta=3

Express the HCF of 963 and 657 in the form of 963x + 657y find the value of X and y.

We need to find the H.C.F. of 963 and 657 and express it as a linear combination of 963 and 657. By applying Euclid’s division lemma, 963 = 657 x 1 + 306.

Since remainder ≠ 0, apply division lemma on divisor 657 and remainder 306

657 = 306 x 2 + 45.

Since remainder ≠ 0, apply division lemma on divisor 306 and remainder 45

306 = 45 x 6 + 36.

Since remainder ≠ 0, apply division lemma on divisor 45 and remainder 36

45 = 36 x 1 + 9.

Since remainder ≠ 0, apply division lemma on divisor 36 and remainder 9

36 = 9 x 4 + 0.

Therefore, H.C.F. = 9.

Now, 9 = 45 – 36 x 1

= 45 – [306 – 45 x 6] x 1 = 45 – 306 x 1 + 45 x 6

= 45 x 7 – 306 x 1 = [657 -306 x 2] x 7 – 306 x 1

= 657 x 7 – 306 x 14 – 306 x 1

= 657 x 7 – 306 x 15

= 657 x 7 – [963 – 657 x 1] x 15

= 657 x 7 – 963 x 15 + 657 x 15

= 657 x 22 – 963 x 15.

Hence, obtained.

Hence x = -15 and y = 22

During the 15 mins reading time, read the question paper prooerly so you will know which section is more easier and which questions you are confident with. So when you start writing start with whichever section you feel easier. Keep the difficult sections for the last and finish off with the ones you are confident with. Also, if uou are not getting the answer to a question, write whatsver you know but dont leave it blank so you MIGHT get marks for steps o something. Hope this helped :)
