Finding the Range of Trigonometric Expression

Explaining the concept by finding the range of 5 sinx + 12 cosx – 13 Comparing (5 sinx + 12 cosx) with (asinx + bcosx)a = 5b = 12√(a2 + b2) = √(52 + 122) = √(25 + 144) = √169 = 13 asinx + bcosx = √(a2 + b2)(asinx + bcosx) / √(a2 + b2) Putting values of a & b ==>5 sinx […]

Inscribed Circle

Let us study a Circle inscribed in Equilateral Triangle and Square First let’s see the Circle in Equilateral Triangle By Pythagoras theorem in triangle BAP BA2 = AP2 + BP2 t2 =  L2 + (t/2)2     L2 =  3t2 /4 L  =  √3 t/2 Again by Pythagoras theorem in triangle BOP BO2 = OP2 + BP2 (L – r) 2 =  r 2 + (t/2) 2 r2 = (√3t/2 – r)2 – (t/2)2 […]

Sternberg’s Information Processing Theory of Intelligence

Information processing is the way an individual decides to go about performing a mental task or solve problems. Sternberg’s work has emphasized the importance of real-world problem-solving and reasoning, and encompasses a broader variety of skills. Sternberg propagated the following steps which he felt an individual uses while processing information. Encoding Inferring Mapping Application Justification […]
