Prove that the angle between tangents from (-2,3) to y² = 8x are at right angles.

Here, the given equation of parabola is y²= 8x.

The equation of tangent to the parabola y²=8x is,

y= mx + 2/m

This tangent passes through the point (-2, 3)

So, 3 = -2m + 2/m

or, 3m + 2m² = 2

or, 2m²+3m - 2= 0

or, 2m² + (4 - 1)m -2 = 0

or, 2m² + 4m - m - 2 = 0

or, 2m(m + 2) - 1(m+2) = 0

or, (m + 2) (2m - 1) = 0

Either, Or,

m = -2 m = 1/2

Required angle is,

कमपयुटर परयोग भइरहेको कूनै दुई कषेतरहरूको नाम लेखनुहोस ।
डिजिटल साकषरता भननाले के बुझिनछ ?
सूचना तथा सञचार परविधि भनेको के हो ?
कमपयुटर हारडवेयरलाई उदाहरणसहित वरगीकरण गरनुहोस ।
कमपयुटरको परयोग आज...

4.कमपयुटर हारडवेयर तिन परकारमा विभाजित छ। तिनीहरू हुन :

इनपुट उपकरण ( माउस, किबोरड, सकयानर)

आउटपुट उपकरण ( मनिटर, परिनटर, सपिकर)

परशोधन उपकरण (सि.पी. यु)

सोरेज उपकरण ( सिडि, पेन.डराइभ)

5.धेरै पहिले, कमपयुटरहरू मुखय रूपमा संखयाहरू गणना गरन र शबद परशोधन गरन परयोग गरिनथयो। समय परिवरतन भएसँगै, कमपयूटरले हामीलाई हामरो दैनिक कारयहरूमा मददत गरनको लागि विकसित गरेको छ। आजकल हामी वयकतिगत रमाइलोको लागि आफनो कमपयुटरलाई खेलको लागि परयोग गरेर र इनटरनेटमा जानकारी फेला पारन परयोग गरछौं। हामरो दैनिक जीवनमा कम...
