Understanding the Equation
In this problem, we need to explore the equation:
(sinA + cosecA)² + (cosA + secA)² = 7 + tan²A + cot²A
Let's break it down step-by-step.
Step 1: Expand the Left Side
- We will first expand (sinA + cosecA)² and (cosA + secA)².
- Using the identity (x + y)² = x² + 2xy + y², we can write:

Understanding Saturated Hydrocarbons
Saturated hydrocarbons are organic compounds that contain only carbon (C) and hydrogen (H) atoms, with all carbon-carbon bonds being single bonds. This means they are "saturated" with hydrogen atoms. They can be either straight-chain or branched, but they do not contain any double or triple bonds.

Read the source given below and answer the questions that follows:In the countryside, rich peasant communities – like the Patidars of Gujarat and the Jats of Uttar Pradesh – were active in the movement. Being producers of commercial crops, they were very hard hit by the trade depression and falling prices. As their cash income disappeared, they found it impossible to pay the government’s revenue demand. And the refusal of the government to reduce the revenue demand led to widespread resentment. These rich peasants became enthusiastic supporters of the Civil Disobedience Movement, organising their communities, and at times forcing reluctant members to participate in the boycott programmes. For them the fight for swaraj was a struggle against high revenues. But they were deeply disappointed when the movement was called off in 1931 without the revenue rates being revised. So, when the movement was restarted in 1932, many of them refused to participate. The poorer peasantry were not just interested in the lowering of the revenue demand. Many of them were small tenants cultivating land they had rented from landlords. As the Depression continued and cash incomes dwindled, the small tenants found it difficult to pay their rent. They wanted the unpaid rent to the landlord to be remitted. They joined a variety of radical movements, often led by Socialists and Communists. Apprehensive of raising issues that might upset the rich peasants and landlords, the Congress was unwilling to support ‘no rent’ campaigns in most places.

Understanding Compound Interest
Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. This makes it different from simple interest, which is calculated only on the principal.

In how many different ways can the word OCCUR be arranged,so the vowel can come together?

Vaishali dasgupta answered • 9 hours ago |
Understanding the Problem
To find the number of arrangements of the word "OCCUR" where the vowels are together, we first identify the vowels and consonants in the word.
- Vowels: O, U
- Consonants: C, C, R
Grouping the Vowels
We can treat the two vowels (OU) as a single unit. Thus, we consider the arrangement of the following units:
- (OU), C, C, R

Read the source given below and answer the questions that follows:In the German regions, a large number of political associations whose members were middle-class professionals, businessmen and prosperous artisans, came together in the city of Frankfurt and decided to vote for an all-German National Assembly. On 18 May, 1848, 831 elected representatives marched in a festive Procession to take their places in the Frankfurt Parliament convened in the Church of St Paul. They drafted a constitution for a German nation to be headed by a monarchy subject to a parliament. When the deputies offered the crown on these terms to Friedrich Wilhelm IV, King of Prussia, he rejected it and joined other monarchs to oppose the elected assembly. While the opposition of the aristocracy and military became stronger, the social basis of parliament eroded. The Parliament was dominated by the middle classes who resisted the demands of workers and artisans and consequently lost their support. In the end, troops were called in and the assembly was forced to disband. The issue of extending political rights to women was a controversial one within the liberal movement, in which large numbers of women had participated actively over the years.
